I bought this latex vest waist trainer from Amazon quite sometime ago to help shed some of the fat on my back. The latex vest waist trainer has the latex in the inside and has a smooth fabric on the outside. For many people, this latex vest would be very comfortable (I think), but for me it's extremely uncomfortable. This latex vest is made to fit the waist, when you purchase it, and read some of the comments, you'll find that if you're really busty, it won't close underneath the bust. So when you're wearing it, it tends to rise up from the bottom and bunch up around the top. If I were able to fasten it underneath the bust, it probably would stay in place around my waist, instead it rides up in the front and I have to keep pulling it down.
