Most tees are defined by their body.

A mock-neck is defined by one thing: the collar that stands up at the throat.

Get it right, and the shirt reads elevated, minimal, and considered.

Get it wrong and you get a limp band that folds the wrong way after the first wash.

We make these on the floor, so this guide is the construction, not the mood board.

Below is how a mock, a high-crew, and a turtleneck actually differ, how we get a collar to stand without choking anyone, and the spec sheet we sign off from before bulk.

01 · Define the neckline

Mock, turtleneck, high-crew: it’s all about height

These three names get used loosely, and that’s where briefs go wrong.

They’re the same idea: a collar that stands at different heights and with one key behavior difference: does it fold, or not.

The short version:

  • Mock neck: a short stand collar, roughly 3-5 cm finished. It stands up on its own. It does not fold. This is the workhorse elevated tee.
  • High-crew / funnel: taller than a mock, around 5-7 cm, still unfolded. Reads more deliberately, with a touch more fashion.
  • Turtleneck tall enough (10 cm+) that it folds back over itself. Different animal: it needs length for the fold and more to pull over the head.

Lock the name and the finished height on the tech pack. “Mock neck” without a centimeter is an argument waiting to happen at the sample stage.

This page is the mock-neck deep dive for how collars are built across every neck type, attachment, taping, and the full method.

Our t-shirt collar construction guide is the parent resource.

02 · The signature detail

Standing the collar without choking the wearer:

Here’s the tension in a mock neck, literally.

The collar has to do two opposite things at once.

It has to stand up under its own weight; otherwise, it flops.

And it has to sit loose enough around the throat that nobody feels strangled at the desk.

Those pull against each other.

A collar stiff enough to stand proud is easy to make too tight.

A collar comfortable enough to breathe in is easy to make too soft to stand.

The build is the balancing act.

Three levers that make it stand:

  • Height vs. recovery. The taller the stand, the more the fabric has to fight gravity. A short mock can stand on ordinary rib. A high-crew needs denser ribs or a stabilizer or it caves.
  • Top-edge circumference. The opening at the top of the collar is what sits against the neck. Too small and it chokes; too wide and it gapes away from the throat and loses the clean line.
  • Finish at the top. A folded (doubled) top edge gives the rim body and stops it curling. A single bound edge is lighter but more prone to rolling.

House concept · Stand Ratio

We read every mock against a quick internal check we call the Stand Ratio: collar height measured against rib depth and recovery.

A tall stand on shallow, low-recovery fabric fails the ratio; it’ll fold or sag. A tall stand on deep, high-recovery rib passes.

It’s not a formula; it’s a sanity check the sample room does before we cut bulk. (Strip this name if you don’t want it in the house glossary.)

The comfort side is a circumference decision, not a mystery.

We set the collar’s finished top opening to clear the neck with ease and confirm it on the fit sample against a real body, not a form.

If the wearer notices the collar at all, it’s too tight.

03 · Collar fabric

Rib collar vs. self-fabric collar:

The collar can be built from ribbing a stretchier, springier knit or from the same jersey as the body (“self-fabric”).

They behave differently and they read differently. This is the choice that most changes how the finished mock looks and lasts.

  Rib collar Self-fabric collar
Recovery High springs back to shape Lower relaxes over time
Stands at height Cleanly, even tall Best kept short
Look Defined, classic, sporty-to-refined Softer, relaxed, vintage
Risk Can look “athletic” if too heavy Sag/roll if unstabilised
Best for Elevated, structured mock Soft, casual mock

Rib: the default for a clean stand

Rib knit (commonly 1×1 or 2×2) has elasticity built into the structure, so it recovers after being stretched over a head and holds its stand through wash cycles.

A 2×2 rib reads denser and more structured than a 1×1.

For most elevated mocks, rib is the safe, clean answer.

How the rib itself is knit and finished is covered in our rib knit guide.

Self-fabric: softer, riskier

A self-fabric collar uses the body jersey, so the whole neckline reads as one soft, continuous piece.

It’s the right call for a relaxed, washed-up, unsporty tee.

The trade-off is recovery: the jersey doesn’t spring back like the rib, so a tall self-fabric stand will slump.

Keep self-fabric mocks on the shorter side and stabilize the attachment.

Rule of thumb: the taller the stand you want, the more you should lean. Save self-fabric for low mocks where softness is the point.

04 · Hold its shape

Attachment and recovery: keeping the stand after the wash

A collar can be the right height and the right fabric and still fail at attachment.

The general mechanics of stretch ratio, neck taping, and seam choice apply to every neckline, and we cover them in full in our t-shirt collar construction guide.

What matters for a mock specifically is one question: does the stand come back after the wash?

How does attachment hit a stand?

Two attachment faults show up differently on a stand than on a flat crew.

Over-stretch the collar as it’s sewn, and a stand doesn’t just ripple; it flattens and loses height.

Skip the back-neck tape, and a stand doesn’t just gape; it slumps forward within a couple of months.

So on a mock we hold the stretch ratio tighter and treat neck tape as mandatory, not optional.

Recovery is a wash test, not a promise:

Recovering the stand returning to full height after being pulled over a head and laundered is easy to claim and only proven in the machine.

We wash-test the sealed sample and re-check the stand afterward.

If it comes back standing, it ships. If it comes back tired, we change the rib or the ratio before bulk, not after.

05 · Body weight

Fabric weight for an elevated tee:

The neckline sets the tone, but a flimsy body undercuts it.

An elevated mock wants a body with some structure, a jersey that hangs with weight instead of clinging.

A thin, papery tee with a sharp collar reads like a mismatch.

As a starting point we build these on a mid-to-heavy jersey, thinking 200-240 gsm so the body drapes cleanly and carries the minimal, considered look.

The neckline is promising. The collar rib is usually a touch heavier or denser than the body so it has the structure to stand.

Too light on the body and the shirt looks cheap under a good collar; too heavy and a tall stand starts to feel like a lot of fabric at the throat.

Weight isn’t a standalone choice; it interacts with drape, opacity, and cost.

If you’re weighing tiers, our crew-neck construction guide and the wider fabric-weight material on the hub break down where each gsm band lands.

For the mock specifically: pick a weight that lets the body match the collar’s confidence.

06 · Silhouette

Fit: fitted mock vs. relaxed mock

The same neckline reads completely differently depending on the body it sits on.

The collar is the constant; the silhouette is the styling decision.

Fitted mock:

A closer body under a mock reads sleek and refined in the 90s-minimal, layering-base register.

It’s the version that goes under a jacket or an overshirt and disappears cleanly.

The collar’s job here is precision.

Relaxed / boxy mock:

A roomier body with a dropped shoulder pushes the same collar into streetwear.

The mock softens and elevates an oversized silhouette that would otherwise read as a basic boxy tee; the oversized guide owns the block and drop itself; here we’re only pairing it to the neckline.

This is the more common ask on our floor right now.

Either works, but the body block, shoulder, and length all shift with the choice, so it has to be decided before grading, not after.

Our t-shirt fit & grading guide covers how the silhouette holds across a size run so the mock reads the same in XS and XXL.

07 · Branding

Decoration on a minimal tee: keep it quiet

The whole point of an elevated mock is restraint, so a loud chest print fights the garment.

The branding that suits this tee is subtle, tonal, and placed where it doesn’t break the clean line.

  • Tonal woven label: at the nape or hem, the brand is present, the color is matched, and it is nearly invisible.
  • Debossed / embossed: or tonal embroidery texture instead of contrast.
  • Small heat-transfer or tonal print: a low nape hit, a sleeve mark, or a hem tag rather than a big front graphic.
  • Interior neck print: branding inside the collar stand where only the wearer sees it.

The rule: if the decoration is the first thing you notice, it’s wrong for this tee.

Let the neckline and the fabric do the talking, and keep the logo tonal.

08 · Action close

The mock-neck spec checklist: quote from this

Bring these decisions, and a quote is fast and accurate.

Leave them open and you’ll go back and forth.

Every line is a value we need on the tech pack before we cut a sample.

  1. Neckline type mock / high-crew / turtleneck (pick one, name it).
  2. Finished stand height in cm, not “short-ish” (00 cm).
  3. Collar fabric rib (1×1 / 2×2) or self-fabric.
  4. Collar top finish with folded/doubled edge or single bound.
  5. Top-edge opening comfort circumference confirmed on body.
  6. Attachment stretch ratio specified, not left to the operator.
  7. Neck tape type and placement (back-neck minimum).
  8. Body weight gsm (200-240) and knit.
  9. Silhouette fitted or relaxed/boxy (decided before grading).
  10. Recovery test post-wash stand check on the sealed sample.
  11. Decoration method and placement, tonal by default.
  12. MOQ & sampling from 50 units per colorway samples in 7-10 days.

Sign-off rule: the collar height, the rib spec, and the recovery test go on paper and get confirmed on the sealed sample. A mock that passes on the tech pack but fails the wash test is not approved.

Common mock-neck questions

A mock neck is a short stand collar that stands on its own and does not fold.

A turtleneck is tall enough to fold back over itself.

A high-crew or funnel neck sits between them taller than a mock but still unfolded.

Usually the collar fabric has too little recovery for its height, or it was attached over-stretched.

A denser rib, a stand height the fabric can actually hold, a controlled stretch ratio, and neck tape fix it.

Prove it with a post-wash recovery test before bulk.

Yes it reads softer and more relaxed. But self-fabric recovers less than rib, so keep it to lower stand heights and stabilize the attachment.

For a tall, crisp stand, rib is the safer build.

A mock is typically 3-5 cm finished tall enough to stand, short enough not to fold.

Above that, you’re moving into high-crew/funnel territory.

Lock the exact height on the tech pack rather than describing it in words.
