Cotton
Cotton is an incredibly hard wearing and easy to care for fabric. It’s the only fabric we wouldn’t mind putting on a warm wash (although we always recommend cold).
We use cotton predominantly for garments that are close to the body and worn often - warranting more durable qualities.
Like you and I, your cotton loves the sun. Did you know the sun is a natural bleach?
After washing, line dry your cotton in the sun and if you have any areas of concern (a mark, or deodorant stains) let the sun do the heavy lifting.
The longer in the sun, the crisper the cotton.
