I thought this was going to be a godsend. There is one thing I hadn't counted on, though and that is that the seams cut into the hips and give you an indent which looks lumpy because your skin and fat bulge around it. I'm 5'5" and 140, so pretty average. My hips are not wide, but my tummy needs work. The thong felt really tight, uncomfortably so, as if it would cut your cheeks in half. I kept wanting to hike it up to bypass the bulge created from the tightness on the hips, but the thong length prevented it from riding any higher. This would be an excellent product for a woman with very little fat, but then again, a woman with very little fat wouldn't need this, would she?
