This body shaper is designed to truly reshape your lower body. It allows you to redistribute some of your irregularities to a more desirable area. This redistribution becomes more permanent over time. And it reduces your waist up to 3 sizes. The Manufacturer recently modified this style crotch area (between legs) to have velcro instead of the original design with snaps (hook and eye). No Bra included. Sizing Guide: The manufacturer recommends to measure thorax or underbust in inches with a measuring tape (NOT the bra band measurement). It is recommended by the manufacturer to get the same size as the thorax (underbust) measurement, if in between sizes we recommend to go a size up. However, if you have wide hips or a large rib cage, we recommend to go 2 sizes up. For example the thorax measures 32 inches with wide hips or large body frame, size 36 is recommended. If your body frame is proportionate to your measurement, you may go a size up.
