The Wonder Woman Zipper Bandeau Bikini is 80%Nylon/ 20%Spandex with a 100% Polyester lining. Many things come to mind when looking at this bikini. I won't bore you with every thought but one of our Superherostuff employees summed it up as: ONE EPIC BIKINI. The bandeau top has detachable halter straps that transforms this top into a strapless bandeau. It also has that cool zipper design in the center - and it's not just for show! If you are feeling a little saucy you can unzip a little bit... or a lot. The Wonder Woman Zipper Bandeau Bikini bottom has the same zipper feature - and it also is not just for show. But don't worry we won't go there...
