I love these leggings because they're the perfect combination of comfort and compression. I have Spanx, and while they're super flattering, they just aren't comfortable, so I don't wear them much. I have very comfortable leggings in other brands, but they aren't all that flattering. THESE are the best of both!! Slight compression, so very flattering, but somehow amazingly comfortable!! LOVE!! For reference, I'm 5'4", 115, and the small is perfect. Doesn't cut into my waist at all. I'm buying a second pair!
