Jersey Pajamas — Fabric Guide for Sleepwear Brands

The T-shirt knit of sleepwear — relaxed, stretchy and easy to wear.

What it is

Jersey is the plain knit used for T-shirts: one smooth face, one looped reverse, and stretch that comes from the loop structure rather than from any elastic fibre. In sleepwear it is the workhorse for anything that should feel like clothes you already own.

It is sold by fibre blend and by GSM, and both matter. A 140 GSM cotton jersey and a 200 GSM cotton/modal jersey are the same “fabric” on a spec sheet and completely different products in the hand.

Where it fits commercially

Jersey is the accessible entry point in a range: comfortable, familiar, easy to price, and forgiving on fit because the stretch absorbs sizing variation. It is also the easiest fabric to print on, which makes it the natural home for seasonal graphics and character licensing.

Where it loses is presentation. Jersey does not photograph as a premium fabric, and it will never carry the sheen or fall of satin or modal.

The three failures worth checking

Opacity. Light jersey in a pale colour is often more transparent than the buyer expected. Check on a body form, in the actual colour.
Side-seam twist. Appears after washing, not before. Always ask for a washed sample.
Wavy hems. A hem stitch that is wrong for the fabric weight looks fine on day one and ripples permanently after laundering.

What to confirm before bulk

GSM and blend ratio in writing, not “soft cotton jersey”
Washed shrinkage in length and width, plus a twist measurement
Opacity in your lightest colourway
Hem and neckline stitch construction on the approved sample

Properties

How it behaves

Fibre type: Cotton, cotton/modal, cotton/polyester, or any of these with 3–5% elastane
Construction: Single jersey knit — one smooth face, looped reverse. Interlock and rib are the heavier relatives.
Weight: Specified in GSM. Light jersey is cheap and cool but can be see-through and curls at the edges; mid-weight jersey is the practical sleepwear range and lies flat when hemmed.
Hand feel: Soft, familiar and casual — the same feel as a well-worn T-shirt.
Stretch: Good mechanical stretch across the width. Elastane is added when recovery matters, for example in fitted tops and waistbands.
Drape: Relaxed rather than fluid. It follows the body loosely without clinging.
Breathability: Good in cotton-dominant blends; falls off as polyester content rises.

Production Notes

What to plan for

The practical consequences of choosing this fabric — the things that decide whether a bulk order goes smoothly.

Shrinkage considerations: The classic knit problem is length shrinkage plus twisting at the side seam after washing. Both are controlled by relaxing the fabric before cutting and by checking a washed sample rather than a fresh one.
Printing & dyeing: Takes screen and digital printing well. Stretch during printing can distort fine registration, so approve a strike-off on the real fabric if the artwork has tight detail.
Sampling considerations: Approve fit only on a washed sample. Ask specifically for a side-seam twist check — it is invisible on a fresh sample and obvious after three washes.
Production considerations: Edges curl, which slows cutting and hemming. Coverstitch hems and correct needle choice keep the finish flat; the wrong stitch produces a wavy hem that appears only after laundering.

FAQ

Fabric questions we get asked

How much does a pajama sample cost?

Sample cost depends on the style, fabric and customization (printing, embroidery, special trims). We confirm the exact sample fee per project before sampling starts — share your design through the quote form for a precise figure.

How long does sampling take?

Sampling time depends on style complexity, fabric availability and the number of revision rounds. We confirm a sampling timeline with each sample order and keep you updated through development.

Can I use my own pajama design?

Yes. Send a tech pack, reference sample or reference photos and we handle pattern development, grading and sampling to your design. Your designs stay confidential to your project.

Will my fit sample be washed before I approve it?

Yes — we launder fit samples before sending them. Cotton shrinks, knits relax and viscose can distort, so a sample approved unwashed is not the garment your customer receives. Approving fit on a washed sample removes the most common cause of bulk fit complaints.

Can you source custom fabrics?

Yes. Beyond stock cotton, modal, satin, jersey, flannel and viscose options, we source custom blends, custom-dyed colors and custom prints. Custom-developed fabrics carry higher minimums, which we confirm during quoting.

Can you match Pantone colors?

Yes. For custom-dyed fabrics we produce lab dips against your Pantone reference for approval before bulk dyeing, so the production color matches the approved standard.
