I've probably bought a total of 6 body shapers since having my twins two years ago and they have all failed! But I finally found the golden ticket! I am 5'4, 175 lbs and have a major postpartum belly due to carrying twins and having a C section. I purchased the XL and it hides my belly giving me a booty and a waist! Buy the thong with the zipper TRUST ME! And wear underwear.
