Collection: Women's Underwear — oh-so-cute undies Organic cotton (90–95%) and at least 70% recycled nylon.

Women's underwear at Organic Basics

Our women's underwear ranges from briefs and thongs to shorties and hipsters, in sizes XXS to XXL and up to XXXL or XXXXL on most styles. The largest group is cotton, made with 90% to 95% organic cotton and a little elastane for stretch. Pick the cut you like first, then the fabric.

Is our cotton underwear 100% cotton?

No. Our cotton underwear is made with 90% to 95% organic cotton, and the rest is elastane, which gives each pair its stretch. The Core styles are made with 95% organic cotton, the Flex styles with 91%, and the Core Icon and Flex Lace styles with 90%. Using organic cotton instead of regular cotton has the potential to build soil health, as it is grown without the use of synthetic fertilizers.

Which cut should I choose?

Women's briefs are the biggest group: the classic Core Briefs, high-leg briefs such as the Core High-Leg Briefs and the Smooth High-Leg Briefs, and the Core Icon Brazilian Briefs. Women's thongs run from the Core Thong and the Flex Thong to string styles like the Core String. Shorties have a fuller, boy-short cut that covers more, and there are hipsters too. For something in between, there are tanga styles: the Core Tanga, the Mesh Tanga Briefs and the Easy Tanga.

Organic cotton underwear

For the highest organic cotton content, the styles made with 95% organic cotton are together on one page: organic cotton underwear (95%). Every cotton style, from 90% to 95%, is here: underwear made with 90–95% organic cotton. If you want an easy everyday pair, the Core Briefs and the Core Shorty are the styles with the most colors to choose from.

Underwear in other fabrics

Not every style is cotton. Others are made with 70% to 91% recycled nylon, among them the Smooth, Mesh, Bare and Naked Rib styles. The Soft Touch styles are made with 95% TENCEL™ Lyocell, the Pointelle and Seamless Waffle styles with 62% to 72% LENZING™ ECOVERO™ Viscose, and the Easy Tanga pairs 48% TENCEL™ Modal with cotton. Each product page lists the exact fabric composition.

Sizes

Every underwear style comes in XXS to XXL, most go up to XXXL, and the Core Briefs, Core Thong, Core Rib High-Leg Briefs and Smooth Thong go up to XXXXL. Fit varies a little between cuts of underwear, so check the size guide on the style you like.

Bras to go with them
