If you are looking for a one piece that keeps everything in place this will be sure to please. Just like our bikini bottoms, it magically turns a pointy poker into a dainty dune. No tucking required. Made of the highest quality compression spandex and mesh this one-piece has adjustable straps to get that perfect fit.
Adults, tweens and teens can experiment with various levels of shaping wIth the innovative RUBIES Shaping Chest Pads that can be ordered separately.
Now available in two sizes: regular and tall, to accommodate taller people and longer torsos.
First time ordering RUBIES? We recommend you use our Size Guide to get the right fit.
