I've purchased a number of slimming garments and this one is my favorite.  Most thigh slimmers leave a very telling mark on the wearer's leg, but these are very smooth and the lace is very pretty.  Like other commenters, I removed the second layer; it was hot, uncomfortable and made the slimmer thicker than I wanted it to be.  Removing the second layer did decrease the slimming just a bit, but it was evened out by the decrease in the amount of material under my clothes.  Mostly, I just wanted something that would smooth out my behind under dresses and skirts and not show a clear line on my thigh and this product did the trick!
