I love getting a bang for my buck so whenever I can find several uses for things I'm happy. I love American Apparel body suits and not only can they be worn as a shirt with shorts, a skirt, or a pair of pants but they can be worn as a swimsuit.
The body suit above can be found at http://store.americanapparel.net/rsa8312.html?cid=30 This is very interchangeable and can be worn with almost any bottom. Below I paired it with a high waisted skirt.
This strapless body suit like the halter can be wore with ANYTHING. I really enjoy wearing thing as a swimsuit. It has a cheeky bottom and a little bit of your tush peeks out. http://store.americanapparel.net/rsa8325.html?cid=30
