The 17 Hottest Swimsuits of the Year, From Cutouts to Plunging Necklines

Beach Riot Celine Shine One-Piece ($148)

A bit of sparkle is never a bad idea, which is probably why we love the look of this cutout one-piece so much. The side slits on this sexy bathing suit will definitely turn heads, and they'll also help to promote airflow and create a more breathable fit. The style comes in several pretty shades, but we like the green coloring the best.
