First, this is good. Good meaning that it did fit me but I order 1-2 sizes up. I usually wear an L-XL and I ordered a 2x.Even though I lucked out and it fits me PERFECT, I used my judgement on past experiences. Also, the item is a little thick so it can be seen under thin clothes.Other than that, this thing is GREAT! My bum looks pretty nice!Went off the size chart but fits a little too big. Doesn't push up enough. But nice material.Im a thick girl Im 200lb and I have big butt with thighs I got it in a 2xl hoping it would be big enough so wrong had to wiggle them up but my butt didn’t completely make it in the holes of the panties clearly I didn’t get the correct size. They did give me a strange shape on my hips but that’s cuz they didn’t fit properly.For someone who has larger thighs, this causes a weird indent between my legs and butt. Can't wear a tight outfit with it or it's obvious I have a butt lifter onFollowed the sizing chart and the shorts fit around the thigh but not enough compression for the cheeks.The fit is somewhat small, when you first have it on, but as time goes on it will stretch.Please do Not waste your $ on these like I did...They fit just fine but my goodness they’re the most uncomfortable thing you could ever imagine! There’s 2 horizontal long plastic pieces that separate your butt cheeks and it kills my tailbone! Not only that but it separates your butt cheeks way too much! Like...unnatural torture device!! I can’t sit or stand wearing these things!! Ouch!!! Also, they are totally noticeable under fitted leggings!! There was no way to adjust the fact that you can see something doesn’t look quite right around your thighs! What a disappointment ?Not sure but i did give a little lift.
