7 best cotton pyjamas I've tested in the summer heat
The best cotton pyjamas: alongside silk pyjamas, one of the more luxe options when it comes to nightwear, and an essential if, like me, you run hot.
My boyfriend, historically, hasn't been allowed to touch me after 10pm unless he wants to prompt loud complaints about my core temperature. Turns out I just had the wrong pyjamas. Previously, picking pairs made from synthetic, non-breathable materials like polyester, it's no wonder I often endured broken sleep, waking up every few hours to move my leg out from under the covers. Now, as a girl who exclusively wears cotton pyjama sets, I can confirm that they solved most of my issues.
But which brand does it best? Thankfully for you, I've spent the last three months testing a host of super-soft cotton pyjama shirts and shorts — including breathable bridal pyjamas and luxury pyjamas crafted from organic materials — to see which I rated best. Why? To spare you countless sleepless nights — or evenings spent scrolling virtual aisles.
So, read on to discover the best brushed cotton pyjamas for women in 2026, including new-in, short sleeve styles and long pyjamas the likes of Calvin Klein, Marks & Spencer and The White Company. Plus, answers to common FAQs about women's pyjamas from a nightwear expert. And if you're on the hunt for a high-performing dressing gown, lingerie, or loungewear, I've got you covered here, too.
Ahead, the best cotton pyjamas for women that I've tried.
For those wanting to lean into the boho dress trend, make Free People your first stop. However, my friends are always surprised when I recommend the retailer when shopping for luxury pyjamas, too. Take this baby blue set — a great option for brides in need of something blue — that consists of button-up shorts and elasticated shorts. An all-natural blend of cotton and linen, these were the airiest of the pairs I tried — and the most likely to wrinkle, although that isn't a major concern for me, considering my pyjamas are rarely seen by anyone other than my partner and postie. Gently oversized, and delicately decorated with eyelet lace trim, this is a pair you could absolutely wear to a hotel breakfast, or over a bikini for a comfy cover-up.
- Sizes: XS (UK 4-6) — XL (16).
- Lengths: N/A.
- Material: 88% Cotton, 12% Linen.
- Care: Machine wash cold.

Pros & ConsPros- Sold as a matching set.
- 12% linen ensures these are super airy and light.
- Slow standard delivery, averaging 7-10 working days.
Cons- These are short-shorts, and so not especially tall-girl-friendly.
Organic Cotton Cheesecloth Embroidered Le Soleil Short Pyjama Set
Want a pair of pyjamas packed with personality? Chelsea Peers delivers every season — and while this cream cotton pair are a tad more neutral than some other pairs on site, it's still finished with unique details, including a vibrant scallop trim, plus fun embroidery on the front and back. Size up once for a more relaxed fit, but don't worry about any shrinking in the wash — these still look brand new despite multiple cycles in my washing machine. And, being not at all see-through, despite being super light and airy, you could absolutely wear this as a sweet summer co-ord, too.
- Sizes: UK 6 — 18.
- Lengths: N/A.
- Material: 100% certified organic cotton.
- Care: Machine wash 30°C.

Pros & ConsPros- Cotton cheesecloth fabric is light, breathable and soft to the touch.
- Matching shorts designed with an elasticated waistband and pockets!
- You can absolutely wear this while wandering around a European city or by the pool.
Cons- Limited size range when compared with some others in this edit.
Cropped Cotton Poplin Pyjama Top
Personally, I like the slight rigidity of poplin cotton — I just feel put together when I'm wearing a pyjama set that doesn't drape to reveal my lack of bra or crease as I breathe. This pair from Calvin Klein are, in my eyes, smart enough to wear out this summer with sandals or flip flops and an oversized tote. However, I also found them suitable for lounging and sleeping. There were complaints from my other half that they were a bit ‘crunchy’ for cuddling, but I didn't feel clammy or claustrophobic once. Only thing worth noting? Size up once as, in my experience, CK comes up small.
- Sizes: XS — XL.
- Lengths: N/A.
- Material: 100% Cotton.
- Care: Machine wash.

Pros & ConsPros- Premium pyjamas.
- Choose from on-trend, butter yellow or a vibrant green.
- Shirt and shorts sold separately — but that does mean you can customise the fit of each.
Cons- Not all will appreciate the cropped cut of the shirt.
Organic Cotton Oversized Broderie Pyjama Set
I'm not even engaged yet, but I know what I want when it comes to bride pyjamas — 100% cotton, rather than sweaty satin, and a twinset I could wear to run around the hotel in for any last-minute approvals. And The White Company has delivered with a broderie shirt and shorts. Crafted from organic cotton and designed with an oversized, boxy cut, they're breathable and comfortable. But you could absolutely throw this duo over your swimwear while on your honeymoon, making it a tad more affordable. While on the sheerer side, I can confirm my nips didn't show through — and neither did my nude-coloured period pants.
- Sizes: XS (UK 4-6) — XL (18).
- Lengths: N/A.
- Material: 100% organic cotton.
- Care: Machine wash.
Pros & ConsPros- Made with 100% certified-organic cotton.
- Boxer-style shorts come fully lined with pockets — and finished with mother-of-pearl buttons.
- Matching nightie also available.
Cons- An investment.
Not all like the ridid, slightly crispy feel of poplin cotton. Thankfully, this pointelle top, while 96% cotton, is blended with elastane for added stretch, making it super comfortable — and accommodating, considering it's normal for our bodies to change during our menstrual cycle. Yes, it's not ideal that you have to buy the matching trousers or shorts separately, bumping up the price. However, for a cosy set of cotton pyjamas you can call on for both lounging and snoozing, this is a smart choice.
- Sizes: XS (UK 6-8) — XXL (16-18).
- Lengths: N/A.
- Material: 96% cotton, 4% elastane.
- Care: Wash on 30ºC and with similar colours.

Pros & ConsPros- Fairly stretchy, accommodating most bust sizes.
- Decorated with a hand-drawn floral print.
- Perfect for brides in need of ‘something blue’.
- Affordable delivery (£2.50, or £3 for next-day).
Cons- A tad expensive, considering you'll have to buy the coordinating bottoms separately.
TBCo. considered every detail before stacking these 100% cotton gauze pyjamas on its virtual shelves. Case in point: the drawstring at the waist has been stitched in so that you don't lose it. And while some might not like the crinkled texture of the fabric, I love that this gives me an excuse not to steam them post-wash, pre-wear. But this pair comes with eco-credentials too, with the buttons made from recycled materials and the brand achieving certified B-Corp status.
The only other thing you need to know? I slept like a baby in these, not once overheating, and didn't wake up once to find the shorts had twisted 360° or the buttons had come undone. I guarantee I'll be taking these on every European vacay for the foreseeable.
- Sizes: XS (UK 6-8) — 3XL (24-26).
- Lengths: N/A.
- Material: 100% cotton gauze.
- Care: Machine wash 30°C.
Pros & ConsPros- Size inclusive, available in every size from a UK 6 to 26.
- Certified B Corp brand — AKA a for-profit company certified by B Lab to meet high standards of social and environmental performance, accountability, and transparency.
- Available in three pastel hues.
Cons- None of note!
Cotton Modal Revere Pyjama Set
I've said it once, and I'll loudly declare it again: Marks & Spencer's do the best cotton underwear. However, after thorough testing, I can confirm the brand deserves acclaim when it comes to nightwear, too. This 50% cotton, 50% modal set felt super breathable and not at all crisp — instead, I was cosy and comfortable all night long. Size-wise, stick with your usual. But further praise is due, considering these are available in three lengths, meaning they'll work for petite and tall girls, too.
- Sizes: XS (UK 4-6) — XL (20-22).
- Lengths: Short, Regular or Long.
- Material: 50% cotton, 50% modal.
- Care: Wash at 40°C, delicate and tumble dry on a medium temperature.

Pros & ConsPros- Made with Cool Comfort technology, I can confirm this pair is thermo-regulating.
- The only pair in this edit is available in multiple lengths: Short, Regular, and Long.
- Super affordable for a full set.
Cons- Just one colourway — although I'd argue this is a universally flattering hue.
Cotton pyjamas FAQs, answered:
“When it comes to our sleepwear, comfort is everything, and cotton delivers it effortlessly,” says Helen, Chelsea Peers' Product Director. 'As a natural fibre, cotton is beautifully soft against the skin, making it an easy choice for winding down at the end of the day. It’s also naturally breathable and absorbent, helping to keep you feeling fresh and comfortable throughout the night."
“One of cotton’s biggest strengths is its versatility across seasons,” continues Helen. "The way it’s woven can completely transform how it feels to wear. Lightweight cottons offer an airy finish that’s perfect for summer lounging.
Taking of Chelsea Peers' pyjama offering specifically, she adds: “Our latest Siesta collection captures that warm-weather feel, with breathable cotton styles designed for laid-back days and lighter nights. Standout pieces, like the Siesta Tiger Print, are crafted from 100% organic cotton cheesecloth, giving them that relaxed, effortless texture that feels light, airy and beautifully breathable.”
“Cotton is also made to last,” details Helen. “Durable and easy to care for, it stands up well to regular washing without losing its softness and wearability, so your favourite sets stay in rotation for longer. It keeps that relaxed, comfortable feel, wear after wear.”

How I choose the best cotton pyjamas:
Considering I already have an extensive collection of pyjamas, I first consulted those — what cotton pairs (or mis-matching separates) do I reach for most? Which pair do I crave when they're sat in the wash basket and in desperate need of a refresh?
However, I've also spent the last three months reviewing as many pairs of pjs as possible — from full-length trouser sets to cotton cami and shorts combos.
For context, each pair (or the same but in a different colourway) was worn for a minimum of two sleeps and then scored against the following criteria:
| Functionality | Were the pyjamas comfortable to sleep in? Are they suitable for both lounging and snoozing? Are they size inclusive? |
| Design | Are the pyjamas aesthetic and comfortable? How many options do I have for colour and pattern? And what percentage of the material was cotton? Did they feel both breathable and cosy? |
| Price point | Are the cotton pyjamas good quality? Is the price for one item, or an entire set? Would I be willing to spend that much again? |
| Delivery | How quickly did the cotton pyjamas arrive, and what were the associated costs? How easy is the returns or exchange process? |
Unsurprisingly, only the cotton pyjamas that impressed made it into this edit. However, I also tried the following, which sadly didn't meet my standards:
- H&M's Cotton Pyjama Bottoms, £22.99 — Despite their 100% cotton makeup, I found these poplin cotton trousers to be a little too stiff to sleep in. Great for lounging (and for tall girls, considering they trailed on the floor for me), but not the highest-scoring in terms of comfort.

Why you can trust me:
I like to consider myself a nightwear expert, considering my personal pyjama collection exceeds 17 pairs. However, I've got professional credentials, too. While I started my journalism career as a writer for a tabloid agony aunt, I quickly pivoted to shopping and have now been a commerce writer for just over three years. In that time, I've found a passion for reviewing the functional — sleepwear, including both luxury pyjamas and silk pyjamas, menstrual health accessories like period pants, activewear and swimwear, whether that be long-sleeve swimsuits or swimwear for big busts.
But to ensure I'm an authority on high-performing fashion and wellness, my working week tends to include multiple press launches, scanning the latest journals, and chatting one-on-one with loungewear designers, gynaecologists, women's health experts, and brand founders to answer common shopping FAQs.
Personally, I fluctuate between a size 12 and 14, depending on where I am in my menstrual cycle. And while I tend to prefer a long-sleeve pyjama set, I branched out in the name of research.
