Does exactly what it’s supposed to do. My husband is obsessed with my butt when I wear these leggings. It personally fit me perfectly. I picked small, and my measurements are 25 waist and 35 hips; I’m 5’3. Some people complained of it being more tight than expected, and honestly, I usually have the opposite problem so this fit comfortably and perfectly without any of the weird crotch gaps that leggings can sometimes do. If you have a problem of things being a bit too tight, then just measurements carefully. The only downside for me is that I really can’t wear underwear without it showing so I just go without. You’ll need high quality no-show underwear and you’ll be good to go if this matters to you. Otherwise, just get it and see for yourself! I walked with these leggings at mid-noon for half an hour and felt just fine afterwards. For me, it achieves it’s full purpose without having any disadvantages that doesn’t usually come with leggings (underwear showing underneath depending on the kind). I’m extremely happy with this purchase.
