Cotton

Soft, breathable and made to move. Discover Calvin Klein cotton underwear for women.

Comfort you can count on

From lounging at home to busy days out, your underwear should feel supportive and comfortable, and that begins with breathable cotton. Calvin Klein ladies’ cotton underwear is thoughtfully designed to combine softness, airflow and lasting wear so you feel at ease from morning to night.

The cotton fabric helps regulate your temperature so you stay cool throughout the day. Added moisture-wicking technology draws away sweat to help you feel fresh and dry, even when your schedule is non-stop. Whether you're navigating a crowded commute, running errands in the heat or winding down after a long day, this quality supports you in every setting.

You can choose from pure cotton jersey for a timeless, natural feel or cotton stretch styles that provide extra flexibility and a closer fit. Every piece is finished with no-tag construction and smooth seams to minimise irritation.

Cotton care made easy

Keeping your Calvin Klein cotton underwear in top condition only takes a few simple steps:

Wash in cold water to maintain the fabric’s natural softness and help each piece keep its shape over time.

Skip fabric softeners if you’re wearing cotton stretch styles, since they can break down elasticity and reduce performance.

Air dry whenever possible to protect the fibres, extend durability and preserve the clean fit you expect from Calvin Klein.
