I love this Vest waist trainer. It does take a little time to attach all the hooks but once it is on I feel great. My posture is so much better and the straps fit perfect around my arms.
It is breathable just as stated. The material is 90% Polyester 10% Spandex. It gives and stretches at the same time stays tight to my body. It is a full Corset Waist Cincher that sits under your bra and goes bellow the belly. It does while wearing give the appearance of looking thinner. I like the straps because it keeps the waist trainer in place unlike others. It has 6 different sizes that you can make larger or smaller depending how tight or loose or how comfortable you want to feel.
