—If you've got to wear jeans, Chrissy suggests denim that's made with a high-cotton content and low synthetic materials. A jean with either a 98% cotton-2% lycra, or 96 % cotton-4% lycra fabric are good combinations.
—For shirts, look for tops made from cotton. Pima and supima cotton are the softest and most breathable blends.
—When you know you're going to sweat up a storm, rayon-blend shirts will keep their shape, even if you decide to take a dip in them.
—When you need to dress up, Chrissy says, "Ditch the polyester blends and look for 100% silk. Another option could be a chiffon (which is made from either silk or nylon), which is also breatheable and light. Look for a lining in an acetate or nylon blend."
And there you go. Happy sweating!
