Cotton underwear

Cotton underwear is an everyday choice: it absorbs moisture well, is breathable, and rarely causes allergies. In this collection, we have gathered women's cotton products - briefs, soft bras, tops, t-shirts, pajamas, and bodysuits.

Pure cotton stretches quickly, which is why underwear manufacturers add a few percent of elastane. This composition retains the properties of cotton while also ensuring the item returns to its shape after washing. For bras, it's worth looking for models where cotton is on the skin side, and the outer side has a polyamide blend responsible for durability.

Cotton shrinks at high temperatures, especially during the first wash. Wash at 40 degrees or lower and avoid tumble drying if you want to maintain the size. White underwear prefers to be washed separately; colored cotton loses intensity after a few washes, which is also affected by chlorine in the water.

Choose sizes according to the tables provided with the products. Shipping in 1-2 business days, free delivery for orders over PLN 199, returns within 14 days.

If you prefer cotton against your skin, check the inner composition: many models have a cotton lining and an outer layer made of polyamide for durability.

Fabric and comfort

Pure cotton stretches out quickly, which is why lingerie makers add a few per cent of elastane. That composition keeps the properties of cotton while allowing the piece to spring back into shape after washing. With bras, look for styles where the cotton sits against the skin and the outer face carries a share of polyamide for durability.

Cotton shrinks at high temperatures, especially in the first wash. Wash at 40 degrees or lower and avoid the tumble dryer if you want to keep the size you bought. White lingerie prefers to be washed separately; coloured cotton loses intensity after a few washes, and chlorine in the water plays its part too.

Choose sizes from the charts shown with each product. Dispatch in 1-2 working days, free delivery over PLN 199, 14-day returns.

If you want cotton against your skin, check the composition of the inner face: many styles have a cotton lining and an outer face with polyamide for durability.

Cotton is what you reach for when underwear has to be worn every day, for hours at a time, with no compromise on breathability. The natural fibre absorbs moisture and lets the skin breathe, which is why it suits people with sensitive skin, women during pregnancy, and anyone who finds lace or smooth microfibre irritating.

When choosing cotton underwear, look at the composition on the label. Pure cotton breathes beautifully, but after a few washes it can stretch and lose its shape. A few per cent of elastane holds the form and stops briefs or a bra shifting during the day. Combed cotton has a smoother, more durable surface than standard cotton, and interlock and single jersey differ in the thickness of the knit: interlock is denser and shows through less.

How to choose your size

What should you watch for? First, the seams - flat, overlocked seams do not print through under fitted clothing. Second, the waist elastic: elastic enclosed in a casing is more comfortable than elastic stitched on top, particularly over a long day. Third, sizing - cotton knit can shrink in its first hot wash, so wash it at 30-40 degrees and keep it out of the tumble dryer.

Which style to choose

Cotton styles cover the full range: from classic full briefs and high-waisted knickers, through boyshorts and men's boxers, to wireless bras and sports tops. If you are looking for underwear for the night or after surgery, go for wireless styles with soft cups. Under a close-fitting dress, a style with smooth-finished edges or a laser-cut edge works better.

Frequently asked questions

Does cotton underwear show through clothing?

Fine cotton jersey can show under fitted clothes. Choose interlock knit or a style with laser-cut edges - then the edges leave no visible line.

What temperature should cotton underwear be washed at?

At 30-40 degrees, on a delicates programme. Higher temperatures and tumble drying shrink the knit and wear the elastic out faster.

Is cotton with elastane still cotton underwear?

Yes. A few per cent of elastane does not change the properties of the cotton, and it noticeably improves how the piece holds its shape after washing.

Which underwear is best for sensitive skin?

Cotton with flat seams, without lace panels at the leg openings and without metal parts. It is also worth checking that the elastic is enclosed in a casing.
