I just got a couple of these shapers from Delimira last week and have only worn them a couple of times so I can't speak to the longevity of the fabric, but I certainly CAN attest to the fact that just out of the gate, this is the best pair of shapewear bottoms I've ever worn. I'm plus sized and carry most of my weight below the waist in my thighs, hips and booty, so shapewear has been a fact of life for me since forever. For many years I've worn Catherine's shapeware, but unfortunately the version I've been wearing all this time is no longer available so I've been in search of something to replace the ones I have now, which are sadly on their last legs (so to speak!). This Delimira pair is really the most comfortable pair of shaping bottoms I've ever worn. Not only am I a size 20/22, but I also have a petite frame (short arms and legs) and a stupidly long torso, so finding shapewear that fits my particular body shape has always been a challenge. I love this item because it's not only soft and comfortable, but actually fits my long torso from just under the bra line all the way down to the pelvic area. It has a grabby elastic strip around the top so it doesn't roll down like so many of these shaping shorts do, and although it doesn't have a similar strip around the bottom of the thighs, so far it lays flat against my legs and I haven't had any problem with the legs rolling up. (We'll see how that goes over time.) I got both a size 2x and 3x since I wasn't sure which size to get, and both fit fine - I don't actually feel much of a difference between the two sizes, really, so if you're in my size range (5'3"
