What are the clothing policy?

Think its a swim suit but I saw a women wearing a t-shirt so I'm not to sure. Hope its helped with your question x

I was just there 2 days ago. I saw women walking around with almost thongs. The just ask that the males has a built in mesh lining so when they go down the slides they don't get exposed

They don't have much to say sice they have ladies with very little covering to others covering a whole lot. I believe it's as long as it is a bathing suit that wouldn't come off and its secured. However, this is what their rules says: Please note that Aquatica, SeaWorld's Waterpark™ is a family experience, therefore we ask that the appropriate swim attire be worn throughout your visit (i.e., no bathing-suit thongs, please). For the health & safety of all of our guests, children in diapers are required to use waterproof protectors. Appropriate swim attire required, cotton shorts or shirts, sport shorts, cover ups, loose fitting articles, or similar items are not permitted on body slides. Swim wear with buckles, rivets, or any sharp objects are not permitted on body slides. Check each ride's entry sign for specific restrictions.

On the straight down single drop where the floor drops out from beneath you, you cannot have cotton shorts or shirts I dont think. It's a safety thing.
