Wear the kind of the bathing suit you feel most confident in. Your might want to included a rash top if you are little shy about being in the pool with other swimmers. My husband wears one when we go to the beach and pool. Keeps him warm in colder waters and also keeps the sun off him. They are generally form fitting and look great on the guys. Also find out if the pool has rules for swimming caps as you might have to wear one.
