Maybe there was a time when one-piece swimsuits were seen as dowdy or matronly...but, honestly, we can't remember it. One-pieces are essentially the bikini's more flattering counterpart (seriously, they somehow look good on everyone). After seeing the latest trendy cutouts, graphic patterns, and strappy details, you'll forget why you ever wanted a two-piece in the first place. Take a look at the best one-pieces ahead of your tropical getaway-and if you're not going anywhere? Invest in one now, and have something to look forward to for summer.
