This is the best waist trainer I have ever bought! I have 2 others that are nothing like this! One is basically a girdle, and the other claimed to be a waist trainer, but looked like a back brace. However, this underbust, steel boned, corset style wait trainer is amazing! It is latex with mesh, so although it is thick and durable, it is breathable! HUGE PLUS it has 3 sets of clasps so you can tighten it as your stomach starts to shrink. It fits well under clothes giving a beautiful hour glass shape, and with the bones it also helps with posture! Overall a 5 star product for sure!
