→ The clothing sampling process moves through four stages: proto → fit → strike-off → pre-production (PP).
→ The golden sample is the signed, sealed reference your bulk is judged against; it’s your quality contract in fabric form.
→ Expect roughly 2–4 rounds before sign-off; each round costs both money and lead time.
→ Feedback works when it’s anchored to a spec line, a number, and a photo, not adjectives.
→ Rushing sampling is the single most common cause of bulk-quality failure.
Chapter 1
Sampling is the bridge between an idea on paper and a garment made by the thousand.
It is the stage where a factory builds your design a few units at a time, you check it, and you both fix problems while they are still cheap to fix.
A tech pack tells the factory what you want.
A sample proves whether that intent survives contact with real fabric, real machines, and real hands.
The gap between the two is bigger than most new brands expect, and sampling exists to close it.
Think of it this way:
Your design has assumptions baked into it: a certain drape, a certain shrinkage, a print that sits exactly where you drew it, and a fit that flatters the body.
Every one of those assumptions is a guess until a physical sample tests it.
Sampling turns guesses into confirmed facts before you commit money to bulk.
It would be faster to skip straight to production.
It would also be a gamble with your entire order.
Here is what sampling is actually protecting you from:
We treat the first sample as a conversation, not a verdict.The point of a prototype is not to be perfect; it’s to surface every disagreement between what you pictured and what the garment actually wants to be, while changing it still costs one sample instead of a full run.
In bulk, you want everything locked and identical.
In sampling, you want to be ruthless about catching what is wrong.
These are opposite mindsets, and confusing them is where brands get into trouble.
The brand that wants its first sample to already be “the one” tends to under-comment, approve too early, and then meet the same flaws multiplied across a thousand units.
The healthier frame: every sample round is a cheap experiment.
The cost of being thorough now is a few weeks and a few sample charges.
The cost of being lazy now is a bulk run you can’t sell.
We unpack that trade-off fully in Chapter 6.
Sampling goes faster and cheaper when you arrive prepared.
Before a factory can make a useful first sample, it needs a clear picture of what you’re after.
Three things do most of the work:
You don’t need every detail perfect on day one; that’s partly what sampling is for.
But the gaps you leave become questions the factory has to ask mid-round, and every question is a small delay.
A strong starting brief is the cheapest speed-up available.
Yes. Many full-service cut-and-sew manufacturers will help you build or finish a tech pack, then run every sampling round in-house.
Not every factory works this way, though.
A factory that only sews expects a finished, production-ready tech pack on day one.
A full-service manufacturer has pattern makers, a sample room, and decoration in the same building.
It can turn a sketch, a reference garment, or a half-finished spec into a working tech pack and a first proto.
That difference shows up later in how many rounds you burn.
Our Sialkot factory runs cut-and-sew, garment wash, and decoration under one roof, so your pattern, samples, and strike-offs all happen in the same building.
No tech pack? We’ll help you build one first. You can also send a garment you like: we copy its pattern, then adjust it to your specs in the fit sample. For sets, a photo of the set you want is enough to start a quote.
Most styles sample in 7-10 days per round. The sample fee is quoted upfront on your itemized quote, and nothing goes into bulk until you approve the pre-production sample.
Once sampling is signed off, our minimum is 50 pieces per style for most categories, 50 sets for tracksuits, and 100 pieces for sewn caps. See how sampling works with us or our full production process.
New to custom production?
If you’re moving from decorated stock blanks to fully custom cut-and-sew, sampling is the biggest new step in your workflow. Our guide on blanks vs. custom cut-and-sew covers when that jump is worth it.
Chapter 2 · The Sample Ladder
Every well-run sampling process climbs the same ladder.
Each rung answers one question, and you don’t move up until that question is settled.
We call it the Sample Ladder: prototype, fit, strike-off, pre-production, and then the sealed golden sample at the top.
The order matters.
You confirm the concept before you chase fit.
You confirm fit before you commit to bulk fabric and decoration.
You prove everything together before you make the final reference.
Skipping a rung doesn’t save time; it just moves the problem to bulk, where it’s expensive.
Question: Is this the right product?
The proto (also called the prototype, development, or first sample) is built straight from your tech pack to prove the concept.
It often uses available or substitute fabric and stand-in trims because the goal is silhouette, proportion, and construction logic, not final materials.
You’re checking: does the design read correctly in three dimensions?
Are the panels, pockets, hood shape, and overall look right?
Proto rounds repeat until the concept is locked.
Question: Does it fit the body correctly?
The fit sample is sewn to your exact measurements, the points of measure (POM) in your spec, and reviewed on a fit model or dress form.
Each measurement is checked against the spec and compared to how the garment actually sits and moves.
Fit comments come back as numbers (“raise the front pocket 1.5 cm,” “reduce cuff opening 1 cm”), and the sample is revised.
Once the base size is approved, the other sizes are graded from it.
Question: Are the color and decoration right on the real fabric?
A lab dip is a swatch of your actual fabric dyed to match a target color (usually a Pantone TCX reference), approved before bulk dyeing.
A strike-off is a test of your print or all-over pattern on the real substrate; for embroidery, it’s a sew-out.
This rung confirms color match, print placement, hand feel, registration, and that the decoration survives the fabric.
It often runs in parallel with fit so the timeline stays tight.
Question: Will the bulk look exactly like this?
The PP sample is the dress rehearsal.
It’s made in the actual bulk fabric, actual trims, actual color, and actual decoration, ideally by the same line that will run production. Nothing is a stand-in anymore.
This is the sample you sign off against. When it’s approved, it gets sealed and becomes your golden sample.
Many factories also pull a size set (one of each size) here to confirm grading across the run.
The top of the ladder your reference standard
The approved PP sample, signed, dated, and sealed.
It is the physical benchmark every production unit is measured against.
We give it its own chapter next, because it’s the single sample that protects your whole order.
Sealed golden samples from the Gibben Clothing factory floor.
Depending on the order, you may also see:
These aren’t extra hurdles; they’re checkpoints that confirm bulk is staying true to what you approved.
The ladder stays the same: proto, fit, strike-off, PP, then the sealed golden sample.
What changes is what you test on each rung.
Performance garments are worn in motion, on stretch fabric, and close to the body.
So a fitness line usually needs one extra fit round and a few extra tests.
Flatlock and coverstitch seams lie flat against the skin. Bonded seams remove stitching entirely.
Each behaves differently under stretch, so approve the seam type at the fit stage, not at PP.
Elastic, silicone gripper tape, reflective details, and zips should be approved in the same round.
| Check | What you’re looking for |
|---|---|
| Stretch & recovery | Fabric returns to shape after stretching; knees and seat don’t bag out. |
| Opacity (“squat test”) | No see-through when the fabric is fully stretched. |
| Seam strength under stretch | No popped stitches or cracking at stress points. |
| Pilling & abrasion | The surface holds up where fabric rubs: inner thighs, underarms, and straps. |
| Colorfastness to sweat & washing | No fading, bleeding, or transfer onto skin or other garments. |
| Moisture management (only if you’ll claim it) | If you plan to market “quick-dry” or “wicking,” get it tested first. Don’t claim what you haven’t tested. |
A fitness line is usually several styles sharing the same fabrics and colors.
Lock fabrics and lab dips once for the whole line.
Then take one hero style, often the legging or the training tee, through fit first. Apply what you learn before the rest are cut.
Run a size set on every style. Stretch garments grade less predictably than fleece.
We produce tricot tracksuits, poly interlock warm-ups, and bonded tech fleece tracksuits, plus track pants with stripes matched from one trim run, joggers and sweatpants, and mesh and nylon shorts.
Sets are sampled as sets: a proto set to lock construction, then a fit set in your fabric, with the top and bottom fitted together on a body.
Each round takes 7-10 days, and both pieces are cut from one dye lot. See our tracksuit and co-ord manufacturing.
Chapter 3
The golden sample, also called the sealed sample, reference sample, or counter sample, is the approved garment that defines exactly what your bulk order should be.
It’s signed, dated, sealed, and held by both sides.
If a dispute ever arises about quality, this is what settles it.
Everything before this point has been about getting things right.
The golden sample is about recording that you got it right, in a form nobody can argue with.
It’s the difference between “We agreed it should look good” and “Here is the physical object bulk must match.”
A golden sample isn’t just a nice sample. It’s a sample that has been
Because it’s the one sample you don’t experiment on. Once it’s sealed, it doesn’t change. It becomes the fixed point that the entire production run and every quality check is calibrated to.
The golden sample does quiet, important work all the way through production:
When inspectors check production, whether in-line during sewing or at final inspection, they compare units against the golden sample, not against memory or a sketch.
Stitch density, color, measurements, and trims: all judged against the sealed reference.
This is the backbone of a real AQL inspection process.
If bulk arrives and something looks off, you don’t argue about intentions.
You hold the delivered garment next to the golden sample.
The reference is physical and signed, so the conversation is about facts, not opinions.
That protects the relationship as much as the order.
People change. Memories fade. Email threads get buried.
The sealed sample stays exactly as approved, so a reorder six months later still has a true reference even if different people run it.
We seal two identical golden samples and photograph both with the seal tag visible. The brand holds one; we hold the counter-sample, and the photos go in the order file. It sounds bureaucratic. It’s the cheapest insurance in the whole process.
One honest caveat: a golden sample only protects you if it genuinely represents bulk conditions.
Sealing a beautiful handmade sample that the line can’t actually reproduce at speed sets a standard for bulk that will be missed.
That’s why it must come from the PP stage; that’s the way bulk will really be made.
The golden sample protects your first order. Restocks are where sizing quietly drifts.
A new fabric lot shrinks differently. A pattern gets re-cut. A different line runs the order.
Nobody changes your measurements on purpose. Drift creeps in wherever nothing is locked.
The fix is to lock five things before your first reorder. We call it the Restock Lock.
Your graded spec sheet, every point of measure for every size, gets a version number and a date. For example: “Spec v3, approved 12 June.”
Every reorder PO names that version. If anything changes, the version number changes, and you approve it in writing.
Ask the factory to store the approved digital pattern and marker for your style.
Get written confirmation that reorders are cut from that exact file.
Re-drafting a pattern “from the sample” is one of the most common ways sizes shift.
Put allowed variation in the purchase order, not just the tech pack.
A common starting point is around ±1 cm (about ⅜ in) on major body points, with tighter limits on small points such as cuff opening or neck drop.
On our hoodie specs, we hold chest width and body length to ±1 cm, and we grade off washed, finished measurements with shrinkage built in.
Units outside tolerance are then a defect, not a debate.
The same fabric spec doesn’t guarantee the same fabric.
A new dye lot or knit batch can shrink differently, which changes finished measurements even when the pattern hasn’t changed.
Ask for a shrinkage test on every new fabric lot, against a written limit, before cutting starts.
Premium programs commonly hold shrinkage to ≤3% on 100% cotton fleece and ≤2.5% on an 80/20 cotton-poly, tested per AATCC 135.
Write the fabric weight the same way, for example, ±5% of the spec GSM, measured on finished, washed fabric, and agree on an incoming roll-weight check at the head, middle, and tail of each roll.
Keep your sealed golden sample and size set. The factory keeps the counter samples.
On every restock, ask for a TOP sample and compare it against the sealed reference while the run is still in progress, not after it ships.
Put it in the PO. Add one line to your purchase order terms: “No changes to fabric, trims, pattern, or grading without the brand’s written approval.” That single line turns a silent substitution into a documented non-conformance you can reject.
One last habit: treat your sealed sample as an archive. Keep it bagged, unwashed, and never worn.
If it gets damaged, approve a replacement from a fresh PP sample rather than working from memory.
Our size guide covers how size runs are built and graded in the first place.
Once a style is approved, its pattern, colors, and labels stay on file, so a reorder goes straight into production without a new sample.
On sets, we keep the dye recipe and trim specs on file too, so next season’s set matches this one. Reorders also keep the price tier you already reached.
Chapter 4
There is no fixed number of sample rounds.
A simple garment with a clear tech pack might sign off in two rounds.
A complex piece with unusual construction, tricky color matching, and heavy decoration can take four or more.
What matters is understanding what drives the count and that every round costs both money and time.
For a typical custom hoodie or streetwear piece, here’s a grounded expectation:
| Stage | Typical rounds | What you’re paying for |
|---|---|---|
| Proto | 1-3 est. | Pattern making, cutting, and sewing one-off substitute materials |
| Fit | 1-3 est. | Re-sewing to revised measurements each round |
| Lab dip / strike-off | 1-2 per color/print est. | Dyeing swatches, test prints, embroidery sew-outs |
| PP sample | 1 (sometimes 2) est. | Full bulk-condition sample on the real materials |
Add it up, and most orders land somewhere around 2-4 sampling rounds total before sign-off, since fit and decoration often overlap.
There’s no flat price, because the sample fee depends on the style, fabric, and decoration.
At GIBBEN CLOTHING, it’s shown as its own line on your itemized quote before any work starts, so there are no surprise invoices.
On orders of 100 pieces or more, the sample fee comes off your bulk invoice.
For scale: a one-off sample always costs more than the same garment in bulk, because you pay for the setup without the volume.
Even in production, a custom heavyweight hoodie runs near $52 per unit at 50 pieces and close to $40 at 1,500.
Here’s what goes into the sample line on your quote:
| Cost element | What moves it | How it works with us |
|---|---|---|
| Making the sample | Pattern drafting, number of panels, construction complexity | Quoted per style, upfront, before work starts |
| Revision rounds | How close round one lands, and how clear the feedback is | Revisions until it’s right; 7-10 days per round on most styles |
| Lab dip | Custom Pantone shade vs. stock color | Dyed on the real fabric. Custom-dyed shades need 300 pieces per color in bulk, so a stock shade avoids the dye cost |
| Print strike-off | Ink colors, placement, and opacity on your fabric color | Approved on your fabric before bulk printing |
| Embroidery strike-off | Stitch density, thread colors, puff height | Approved before bulk embroidery |
| Wash shade sample | Acid, enzyme, pigment, or garment-dye finishes | Adds time: acid-wash styles take 10-14 days per round |
| Courier | Weight, destination, and speed | Samples ship by DHL or FedEx to your door |
| Reorders | None | No new sample needed; your approved pattern and specs stay on file |
A complete tech pack, a reference sample, consolidated feedback, and lab dips run alongside fit.Every round you avoid saves its sample charge and its freight.
One more lever: put styles in one order. Two styles of 50 make 100 pieces, which credits your sample fee back.
Sampling costs come in a few buckets. Knowing them up front stops the bill from feeling like a surprise:
Sample charges are often credited. Many factories, including us, credit some or all sampling charges against the bulk order once it’s confirmed, so the cost effectively folds into production. Always ask how a factory handles this before you start. Bulk pricing itself is a separate topic we break down in our cost breakdown guide.
The biggest lever is the tech pack.
The clearer your starting brief, the fewer rounds you’ll burn discovering things that could have been specified on day one. After that:
Minimums interact with this too: sampling is also where you confirm the order is viable against the factory’s MOQ before committing.
Chapter 5 · The Three-Anchor Feedback Method
Most wasted sample rounds come from vague feedback, not bad factories.
“The fit is a bit off” or “make the color pop more” can’t be sewn.
A factory can only act on instructions that are specific, measurable, and located.
The fix is a simple habit we call the Three-Anchor Feedback Method: anchor every comment to a spec line, a number, and a photo.
See the detailed guide on how to give sample feedback to your factory.
Anchor 1
Tie the comment to a point of measure or a tech pack reference so the factory knows exactly which element you mean: “front pocket opening (POM 14),” not “the pocket.”
Anchor 2
Replace adjectives with measurements. “Lengthen sleeve 2 cm at the cuff” or “match Pantone 19-4006 ‘TCX’,” never “a little longer” or “darker.”
Anchor 3
Mark the sample physically, pin, tape, or chalk the spot, photograph it, and attach the image to the comment. A marked photo erases ambiguity instantly.
When a comment carries all three anchors, there’s nothing left to interpret.
The sewing team reads the spec line, applies the number, and confirms against the photo.
That’s how you collapse three muddy rounds into one clean one.
A few habits make feedback land:
From our sample room
The single most useful thing a brand sends us is a marked-up photo with a measurement written next to the mark.
It removes an entire layer of back-and-forth.
The brands that sign off fastest aren’t the ones with the simplest garments; they’re the ones whose comments we never have to ask twice about.
A few patterns waste rounds without anyone noticing they’re the cause:
| Vague (causes a wasted round) | Anchored (acts on it immediately) |
|---|---|
| “Sleeves feel a bit long.” | “Sleeve length (POM 8): reduce 2 cm from cuff. See photo 3, marked.” |
| “The hood looks small.” | “Hood height (POM 22): increase 1.5 cm. Compare to the reference sample sent.” |
| “Make the print color richer.” | “Print color: match Pantone 18-1664 TCX. The current strike-off reads too pink.” |
| “The fabric feels thin.” | “Confirm bulk fabric is 380 GSM brushed-back fleece per tech pack, not 320.” |
Chapter 6
If there’s one idea to take from this guide, it’s this: sampling is the cheapest place in the entire process to fix a mistake.
Skip it, compress it, or sign off early, and the mistake doesn’t disappear; it multiplies across every unit in your bulk run, where fixing it costs the most.
Almost every serious bulk-quality failure can be traced back to a sampling step that was skipped or hurried.
Here’s how rushing actually goes wrong.
The proto looked great, so why wait for a PP sample in the real fabric?
Because the substitute fabric lied to you.
Real bulk fleece can shrink differently, drape differently, and feel different in hand.
You find out after a thousand units are cut.
Fabric that isn’t wash-tested can shrink, twist, or bleed color after the customer’s first laundry cycle.
A sample wash takes a day. A bulk run that shrinks two sizes is unsellable.
“Close enough, let’s run it.” A fit that’s 1.5 cm off on one sample is 1.5 cm off on every single unit.
Small, tolerable-looking errors become consistent, returnable flaws at scale.
Without a sealed reference, there’s no agreed standard.
When bulk arrives and something’s off, there’s nothing objective to measure against, just two parties remembering the approval differently.
The math of a mistake. Fixing a flaw on one sample costs one sample.
Fixing the same flaw after bulk means rework, replacement, or scrap across the whole order, plus a blown delivery date and a customer who’s already waiting.
The few weeks of sampling “costs” are almost always cheaper than the alternative.
A real example
A brand once asked us to skip the wash test to save a week before a drop.
We pushed back and ran it anyway.
The fleece shrank more than expected and twisted at the side seam, a problem we fixed by adjusting the fabric finish and pattern before bulk.
Had we shipped on the original plan, the whole run would have shrunk a half-size in the customer’s first wash.
One day of testing saved the entire order.
Deadlines are real, and sometimes you genuinely need speed.
The answer isn’t to skip rungs; it’s to parallelize them.
Run lab dips and strike-offs alongside fit instead of after it.
Lock a clean tech pack so the prototype starts closer to right.
Pre-book bulk fabric so it’s ready the moment the PP sample is approved.
Compress the calendar by overlapping stages and tightening feedback.
Don’t compress it by deleting the checks that protect your order. We map the realistic version of that calendar next.
Chapter 7
Sampling rarely runs on a perfectly fixed schedule, but it follows a predictable shape.
Here’s a grounded week-by-week view for a custom hoodie, assuming a clean tech pack and reasonably prompt feedback.
Treat it as a planning baseline, not a promise; your real timeline shifts with complexity, round count, and shipping distance.
Design, measurements, materials, and decoration locked. Reference samples sent. The cleaner this is, the shorter everything after it.
First sample built from the tech pack and shipped. You review concept, proportion, and construction. Comments returned.
The sample was re-sewn to corrected measurements and re-reviewed. One to three loops depending on how close round one landed.
Color matching and print/embroidery tests approved on the real fabric overlapped with fit to save calendar time.
Full bulk-condition sample on the real materials. Final checks across fit, fabric, color, decoration, and construction.
PP approved, sealed, signed, dated, and duplicated. Bulk production begins against the sealed reference.
So a typical sampling phase runs roughly three to six weeks before bulk starts, longer with extra rounds or long shipping legs.
The single biggest variable isn’t the factory’s speed; it’s how fast and how clearly feedback comes back.
A round can sit idle for a week waiting on comments, then move in days once they arrive.
Plan sampling into your launch date, not around it. Brands that set a drop date first and discover sampling second are the ones who end up rushing. Count back from your launch: bulk production time, then the full sampling phase, then tech-pack prep. That’s your real start date.
Chapter 8 · The Detailed Checklist
Before you approve a PP sample and seal it as your golden sample, every item below should be a confirmed yes.
This is the final gate between sampling and bulk; the moment to be thorough, not hopeful.
Print it, work through it, and don’t sign until each box is genuinely checked.
▢ Measurements. Every point of measure matches the approved spec within tolerance.
▢ Fit. Confirmed on a fit model or form that sits and moves correctly, base size locked.
▢ Fabric. Correct composition, GSM, hand feel, and finish are the real bulk fabric, not a substitute.
▢ Color. Lab dip approved against the physical Pantone reference in correct lighting.
▢ Decoration. Print, all-over pattern, or embroidery strike-off approved for color, placement, and hand.
▢ Trims & labels. Drawcords, zips, eyelets, woven labels, and hangtags are all correct and final.
▢ Wash test. Shrinkage, twisting, and colorfastness were checked after washing.
▢ Construction. Seam types, stitch density, and finish match the spec and survive at production speed.
▢ Grading. The size set was reviewed so the fit holds across the full size run.
▢ Seal & sign. A golden sample tagged with style number and date, signed by both sides, and a counter sample retained.
Download Checklist
Work through this list, and the handoff to bulk becomes calm and boring, which is exactly what you want.
Every “yes” here is a problem that can’t surface later.
The sealed golden sample then carries that approval all the way through production and into final quality inspection.
When a brand and our team walk this checklist together on a video call, holding the PP sample to camera item by item, sign-off becomes genuinely final. Nothing gets “assumed approved.” That ten-minute walkthrough is the best protection against a bulk surprise we know of.
Appendix
Factories move fast and use shorthand.
Here’s a plain-English reference for the terms you’ll hear across the sampling process, so nothing in an email or a call catches you off guard.
| Term | What it means |
|---|---|
| Tech pack | The full specification document for your garment measurements, materials, construction, trims, and decoration. The starting point for the whole process. |
| Proto sample | The first sample, built to prove the concept. Often made in substitute fabric and trims. Also called a development or first sample. |
| Fit sample | A sample sewn to your exact measurements and reviewed on a body or form to confirm fit before bulk. |
| POM (Points of Measure) | The specific measurements that define a garment, such as chest width, sleeve length, and hood height. Feedback should reference these. |
| Grading | Scaling an approved base size up and down to create the full-size run (S, M, L, XL…) in the correct proportion. |
| Lab dip | A swatch of your actual fabric dyed to match a target color, approved before bulk dyeing. |
| Strike-off | A test print of your artwork or pattern on the real fabric to approve color, placement, and hand before bulk printing. |
| Sew-out | The embroidery equivalent of a strike-off: a test stitch of your embroidered design, approved before bulk. |
| Pantone TCX | A standard textile color reference system. Specifying a Pantone TCX code removes guesswork from color matching. |
| PP sample (Pre-Production) | A sample made in the real bulk fabric, trims, color, and decoration: the final dress rehearsal you sign off against. |
| Size-set sample | One unit of each size, made to confirm grading holds correctly across the full size run. |
| TOP sample (Top of Production) | A unit pulled from the live bulk run to confirm production is matching the golden sample. |
| Golden/sealed sample | The approved, signed, sealed reference garment that bulk is measured against. Your quality standard in physical form. |
| Counter sample | The matching copy of the golden sample the factory keeps so both sides work from an identical reference. |
| Tolerance | The allowed margin of variation on a measurement, e.g., ±1 cm, within which a garment still passes. |
| GSM | Grams per square meter: the weight of a fabric. Higher GSM generally means heavier, denser fleece. |
| Wash test | Washing a sample to check shrinkage, twisting, and colorfastness before committing to bulk. |
| Bulk fabric | The actual fabric used for the production run, as distinct from any substitute used in early sampling. |
| Trims | The non-fabric components: drawcords, zips, eyelets, woven labels, and hangtags that also need approving during sampling. |
Keep this list handy through your first few sampling cycles.
Once the vocabulary is second nature, the whole process moves faster; you’ll spend your energy on decisions instead of translation.
It’s the stage where a factory builds your design a few units at a time so you can check and correct it before committing to a full production run.
It moves through four stages: prototype, fit, strike-off, and pre-production, ending in a signed, sealed “golden sample” that bulk production is measured against.
Most custom hoodie orders sign off in roughly two to four rounds total, since fit and decoration testing often overlap.
A simple garment with a clear tech pack can be faster; a complex piece with tricky color or construction can take more.
The clearer your starting tech pack, the fewer rounds you’ll need.
The golden sample is the approved, signed, and sealed reference garment that defines exactly what your bulk order should be.
Quality inspectors compare every production unit against it.
Because it’s physical and signed by both sides, it settles any dispute about whether the bulk matches what was approved; it’s your quality standard in fabric form.
Yes, sampling carries real costs: sample charges, lab dip and strike-off fees, and courier or freight for each round.
Many factories, including us, credit some or all of those charges against the bulk order once it’s confirmed, so the cost effectively folds into production.
Always confirm a factory’s policy before you start.
A prototype proves the concept and is often made in substitute fabric.
A fit sample is sewn to your exact measurements to confirm fit.
A pre-production (PP) sample is made in the real bulk fabric, trims, color, and decoration; it’s the final dress rehearsal you sign off against before it becomes your golden sample.
Anchor every comment to three things: a spec line (which is a point of measure), a number (an exact measurement or Pantone code), and a photo (the sample physically marked).
Replace adjectives like “a bit long” with “reduce 2 cm at the cuff,” consolidate all notes into one sheet per round, and explicitly approve what’s already correct.
For a custom hoodie, the sampling phase typically runs about three to six weeks before bulk production begins, depending on round count, garment complexity, and shipping distance.
The biggest variable is feedback speed: a round can stall for a week waiting on comments, then move in days once they arrive.
Plan sampling into your launch date by counting backward from it.
Sampling is the cheapest place to catch a mistake.
A flaw fixed on one sample costs one sample; the same flaw discovered after bulk means rework, replacement, or scrap across the entire order.
Most serious bulk-quality failures trace back to a skipped wash test, a compressed-fit round, or going straight to bulk from a substitute-fabric proto.
It depends on the style, fabric, and decoration, so there’s no flat price. At GIBBEN CLOTHING, the sample fee is shown upfront on your itemized quote before any work starts, each round takes 7-10 days on most styles, and the fee comes off your bulk invoice on orders of 100 pieces or more. A one-off sample always costs more than the same garment in bulk, because you pay for the setup without the volume.
Yes. Full-service cut-and-sew manufacturers with in-house pattern makers and a sample room can build or complete a tech pack from your sketch or reference garment, then run every sampling round.
Before you commit, ask who owns the final tech pack file, what each sample round costs, and whether the PP sample is made on the bulk line.
At GIBBEN CLOTHING, we’ll help you build a tech pack if you don’t have one or sample straight from a garment you like.
Lock five things before your first reorder: a version-numbered spec sheet named on every PO, the approved pattern files, written tolerances in the purchase order, a shrinkage test on every new fabric lot, and a sealed golden sample plus size set. Then ask for a measurement report and a TOP sample on every batch, checked against the sealed reference.
The stages stay the same, but the testing changes. Use the real stretch fabric from the first prototype, test fit in motion with a wear trial, approve seams and trims at the fit stage, and confirm stretch recovery, opacity, pilling, and colorfastness to sweat on the PP sample. A fitness line typically needs one extra fit round.
