Seamless microfiber targets tummy waist and upper hip area. Optional adjustable 4-point loop and strap system holds the shaper up to the bra line so it will not roll down. Can be used with virtually any bra. Bottom covers the upper hip area (muffin top) and stays in place with a silicone strip and graduated compression. Firm compression will slim and smooth. Euroskins recommends that you select the size based on the largest part of your body the shaper will be on and that you do not purchase a smaller size to reduce your size.
