I was bought this to swim laps in. I have a hard time finding finding one-piece suits that fit, but a lot of two-piece suits are more for fashion than function. This suit looked like it would work for actual swimming, not just sunbathing, and it is perfect--plus it is super cute! I guess I misread the product description, because I thought I was getting a top only, but it arrived with both pieces. I didn't expect the bottoms to fit because I usually need a different size for top and bottom, but to my surprise, both pieces fit great.
