Swimsuits with a deep or plunging neckline, draped swimsuits, solid dark swimsuits, and loud prints can make your body appear thinner. Those with a high-neck at the back are also a good choice as it helps support the breasts and provides a decent amount of shaping. Swimsuits that come with back fat minimizer bras can also help significantly in keeping you comfortable all day. Cropped top swimsuits with off the shoulder designs and an irregular hem can make you look thinner and while swimsuits with lace backs help hide back fat while keeping you cool.
