I'm sorry, but if I am out at the pool/lake/beach with my two young kids, one of whom I need to chase around everywhere, I don't want my butt hanging out of inadequate swim bottoms (and no bikini bottom adequately covers up this booty).
Also, I hate how board shorts look on me. I have curves, and I've never found a single pair of board shorts that flatters my figure. So, I think this is a perfect idea for moms of littles, or women who just prefer to remain covered for any reason. Plus, if you have to jump in the water to rescue your wild 1-year-old, they are waterproof, just like board shorts.
These swim shorts come in three different lengths, including a shorter version of the one pictured.
