A suit with eye-catching details above the waist―a pop of color, a deep neckline, hardware―to lure attention to your upper half. Down below, opt for an arched leg line that hits about an inch south of the hip bone. A skirted bottom also hides hips, says Ilene Sofferman, manager of Canyon Beachwear, in New York City. An A-line cut, a slit, or ruched sides keep the look modern.
What to avoid: Boy shorts, one-pieces with side cutouts, and bottoms with embellishments, especially ring hardware (which can pinch the skin).
