Nobody likes getting caught with her pants down. For me, it usually happens sometime between Memorial Day and Labor Day: A daredevil vacation buddy convinces me to take a late-night swim — and I realize I’m not wearing a swimsuit. Which is where beach-friendly lingerie label Xirena comes in. Designer Dierdre Roffoni was on a similar wavelength when she created the label, which features bodacious cuts, bright prints, and opaque metallic panels in strategic (read: otherwise see-through prone) places. Bikini and thong bottoms and triangle and sporty tops stay put underwater, but you should be ready to show skin when (and if) they’re the only thing you’re wearing. You never know. —Tiffany, Everywhere editor Available at revolveclothing.com, $44-$98.
