An extra-firm compression latex waist trainer that sculpts your curves, making you look up slimmer. It has an open bust design so you can wear your own bra. This innovative vest is made of three fabric layers. An ultra-light layer of latex provides extra-firm compression, while an inner layer of stretch cotton keeps you comfortable and protects your skin from the metal of the front hook-and-eye closure. Flexible front, side, and back boning keep the waist trainer in place while creating an hourglass look. You can wear it daily, or while working out to help you sweat more.
