Crossfit girls, what do you wear while working out?

Hey, so I have trouble finding the best activewear / something that would make me feel comfortable, not drenched in sweat, shorts that don't ride all the way up and make me self conscious. I don't want to wear tights because it is too hot and I don't want to wear tank tops because they make me uncomfortable. Anyways, I really want to know where I can get t-shirts and shorts like the ones the referees in the crossfit games wear.
