Waist trainers are, for all intents and purposes, the classic girdles, but with a corset type design that focuses on molding (shaping)only the waist. Some design variations come with bras and/or adjustable straps that help enhance the bust. Daily wear waist trainers look great and feel comfortable under any type of clothing. They are made of materials with up to three levels of compression (soft, medium and high) designed to shape your body and stylize the curves to your liking. The most used textile fibers are Powernet, Nylon and Lycra.
