I ordered one of these bi/tri suits from Skins -should be arriving tomorrow. Can't wait to try it on. They processed the order and shipped it pretty fast, so no complaints about the shopping experience so far.

They're a little light on design variety, but the prices seem fair. I just hope they change up the patterns and color selection frequently.
