Muslin Cotton Pajamas Made for Slow, Unhurried Mornings

Muslin cotton pajamas feel different from ordinary cotton sleepwear: the crinkled double-gauze weave traps a little air between its layers, so a set feels weightless in summer and gently warm when the temperature drops. Every pajama in this collection is cut from 100% natural cotton or muslin, most with breathable, skin-friendly finishes and relaxed elastic waistbands, and each order ships free within the US with our 100-night guarantee behind it. You will find long-sleeve sets for cooler months, shirt-and-shorts sets for warm nights, playful prints from cherries to polka dots, and a sleeveless nightgown for the heat of July. Because muslin has no stretch, our size charts matter — when in doubt, go one size up for the classic loose fit.

The easiest way to shop sleepwear is by the night you are dressing for. For warm evenings, short sets dominate: The Short Bloom pairs a ruffle-collar top with shorts in three floral prints, and Nuvell does a peach-print version with white piping that runs up to size 3XL. If you want the simplest possible starting point, The Muslin Cotton Pajama is the classic shirt-and-shorts silhouette in four soft pastels — the set we would hand to someone trying muslin for the first time.

For cooler nights, look to the long-sleeve sets. The Long Sleeve Pajama keeps the same airy gauze but covers you to the wrist and ankle, while Flora — a short-sleeve top with long pants — is naturally breathable, hypoallergenic and printed in four ditsy florals. Heirloom Bloom leans romantic with botanical bouquets on cream, and The Muslin Dot is the most tailored of the group: crisp polka dots with contrast piping, in both short-sleeve and long-sleeve fits.

Prints are where these sets show their personality. Hearts run through the Heartline and Heartly cotton sets, cherries through The Cherry, and trailing vines through The Bloom. None of it reads as loud in person — the prints sit on soft, washed-out grounds that look intentional rather than novelty.

Two practical notes before you order. First, sizing: muslin cotton has no stretch, so every product page carries its own measured size chart — measure your chest and hips against it, and size up if you land between rows. The relaxed cut is part of the design. Second, care: wash cold, and for most sets skip the tumble dryer entirely (each product page states its exact care line). Treated that way, the double gauze crinkles beautifully, never needs ironing, and gets noticeably softer month after month. And if a set does not suit you once it arrives, our 30-day return window and 100-night guarantee both apply — sleep on the decision, literally.

What does muslin cotton sleepwear feel like?

Light, airy and slightly crinkled — the double-gauze weave holds a thin layer of air, so it stays cool on warm nights and comfortable in cooler ones. It is naturally breathable, gentle on sensitive skin, and softens further with every wash.

How do the pajama sizes run?

Muslin has no stretch, so fit comes from the cut, and comfort ease is already built into our measurements. Check the size chart on each product page and choose the size your chest and hip measurements fall into — if you are between sizes, go one up.

How should I wash these pajamas?

Machine wash cold and avoid fabric softener and ironing. Most muslin sets should not be tumble dried — each product page lists its exact care instructions. The crinkled texture is part of the fabric, so there is nothing to press flat.

Can I return a set that doesn't fit?

Yes. Returns are accepted within 30 days of delivery for unworn sets in original condition — email our support team first for a return authorization. Every order also carries the 100-night guarantee against tears or splits in normal use.
