Quick answer

Choose a pyjama by matching the fabric to your sleep temperature, the cut to your movement habits, and the size to your largest measurement, not your smallest. For a breathable, low-fuss option, look for a Tencel® top like the softness-260163-820-b59965de9527706fb049b317-1039664">softness-260113-670-c9feabce4f8216845620e2c4-1039656">softness-260113-820-4ffb907712495e656d45c853-1039629">softness-260113-04-bd122bd51c924d03d286aaf9-1039627">SOFTNESS pyjama top; for a supportive, seam-free sleep bra, the NUFIT spacer bra is a strong pick. Always check the size chart and prioritise comfort over a snug look.

Start With Fabric, Not Style

The fabric determines how a pyjama feels after two hours, not two minutes. Tencel® is a smart choice for women's sleepwear because it is ultra-soft, breathable, and comfortable for both day and night wear, as seen in the SOFTNESS top. If you sleep hot, avoid heavy synthetic blends that trap moisture; if you sleep cold, a slightly denser knit will hold warmth without bulk.

Look for finishes that stay smooth against the skin. Openwork details, like those on the sleeves and collar of the SOFTNESS top, add visual interest without adding scratchy seams. For bottoms and sleep bras, seam-free construction reduces pressure points when you lie on your side.

Match the Cut to How You Sleep

Side sleepers need room through the shoulder and hip; back sleepers can wear a closer cut. If you toss and turn, choose a pyjama with a bit of stretch or a relaxed fit so the fabric moves with you instead of twisting. For the top, a sleeveless style like the SOFTNESS top prevents overheating and layers easily under a robe.

For the bottom, consider a tanga if you want an invisible, second-skin feel under pyjama trousers. The NUFIT tanga is ultra-fine and light, with an elastic tri-band waist that stays put without digging in. If you prefer more coverage, a classic brief or short will feel more secure.

Get the Size Right the First Time

A pyjama size guide is only useful if you measure the right places. Measure your bust, natural waist, and fullest hip over your usual sleepwear, then use the largest measurement to pick your size. If you are between sizes, size up for sleepwear: a little extra room prevents the fabric from pulling across the back or riding up at night.

Pay attention to the model's size as a reference, not a rule. The SOFTNESS top is shown on a model wearing size S (equivalent 36), and the NUFIT tanga is shown on a model wearing size 2 (equivalent 36 or S). Use those as a starting point, then check the specific size chart for each product because fits vary between styles.

Decide Whether You Need a Sleep Bra

If you want light support at night, a spacer bra is a better choice than a push-up. The NUFIT spacer bra has smooth, seam-free cups for a natural shape without added volume, and the spacer knit is breathable and ultra-comfortable. It gives natural support with a feeling of lightness, and the elastic tri-band on the sides helps it stay in place.

For a more sensual option with support, a lace triangle bra with underwire can work if the construction is right. The NUDITÉ triangle bra is made with French Leavers lace and a three-part construction for optimal support, with a lined back and centre. It is designed for larger sizes, so it suits women who need more than a light sleep bra but still want a delicate look.

Check the Details That Affect Comfort

Look at the waistband, straps, and seams. A tri-band elastic waist, like the one on the NUFIT tanga, distributes pressure and reduces rolling. Adjustable straps and a lined centre on a bra, as on the NUDITÉ style, help you fine-tune the fit. If a product does not list a feature you need, such as a specific strap width or a particular fibre content, treat that as a limitation and ask before buying rather than assuming.

Also consider how the pyjama will be worn. A top that works for day and night, like the SOFTNESS top, gives you more value. If you plan to wear the set around the house, choose a cut that looks tidy enough to answer the door; if it is purely for sleep, prioritise softness and breathability over structure.

Decision rules for buying a pyjama

  • If you sleep hot: Choose breathable, lightweight fabrics such as Tencel® or spacer knit, and avoid heavy brushed cotton or thick synthetic blends. Check the fabric content before you buy; if it is not listed, ask.
  • If you want one set for day and night: Pick a top that looks tidy enough for lounging, like the SOFTNESS sleeveless top, and pair it with a discreet bottom such as the NUFIT tanga. A neutral, simple cut gives you more wear per item.
  • If you need bust support at night: Choose a spacer bra for light, natural support, or a constructed lace bra like NUDITÉ if you are a larger size and want more hold. Avoid push-up styles for sleep; they add volume you do not need when lying down.
  • If you are between sizes: Size up for sleepwear, especially in woven or less stretchy fabrics, and use the model's stated size only as a starting reference. Measure your largest area and check the specific size chart for each style.
