PSA for all the beach babes out there: One-pieces are all the rage. Sure, two-piece designer swimsuits like bikinis and tankinis have been among the most popular options on the market, but these one-and-done styles have a way of making us swoon. One-pieces are extremely flattering on every body type and make one hell of a statement in your poolside selfies—especially if you want a little more coverage on the beach. Plus, they offer comfort and all-around functionality (and who can say no to that?!).
