Cotton bras – why we love this fabric for cooling underwear
Silk feels beautifully smooth, lace can be pretty, elastane adds stretch, but nothing beats a cotton bra for breathable natural comfort.
Whether you want to stay cool during warm weather, beat the discomfort of hot flushes in menopause, wear something that’s gentle on sensitive skin, or simply avoid man-made fibres, we believe it’s hard to beat pure cotton bras (or at least bras with a high cotton content).
Some of the best-selling cotton bras in the Royce range combine lightweight cotton comfort with everyday breathable support. Naturally breathable fabrics, such as cotton, allow moisture to evaporate from the surface of the skin rather than trap it (as synthetic fibres can) allowing the body’s own cooling system to work effectively, and stopping you from melting into a sweaty mess on hot days!

Best cotton bras
Royce has been designing exceptionally comfortable cotton non-wired bras since 1991. We love naturally breathable fabrics, so many of our styles feature a high cotton content or super soft organic cotton, making them ultra comfortable and gentle on sensitive skin. When it comes to breathable bras for women, Royce is your go-to.
Here’s our pick of the best cotton comfort bras around…surgery…

Comfi-Bra Front Fastening Cotton Bra
This super-soft, breathable cotton comfort bra continues to be one of our most popular styles (let alone one of our best-selling cotton bras). Made from high-quality cotton with a touch of stretch, it’s non-padded with lightly padded straps, and comes with cotton lining/pockets to hold a prosthesis if required.

Mia Non-Padded Organic Cotton Bra
Could this be the ultimate sleep bra? Organic cotton lounge bra Mia is a crossover style with no fastenings or components, making it soft against sensitive skin. It features dual-cup sizing (from F to JJ), and while the style is relaxed, it still provides exceptional support for larger busts.
