I normally wear a extra large and sometimes a large in my leggins. I got XL but these fit like a large maybe, almost.I would say definitely size up! I will keep then even know they fit tight and it's a struggle to get them on But the color is pretty and they stay up once on, they not going anywhere lol....Im surprised that so many people have left favourable reviews on these leggings. The material is definitely not breathable, I try to submerge it under water and an air bubble will form. And the ridges in the material feels quite odd. From the back it looks like a wedgie has been designed into the tights backside. This, I assume is to give the illusion of a bigger bum. Dont like itThese are so comfortable fitting.I thought it would look like a butt lift, but instead about 5 people asked me if I have a wedgy. Super embarrassed. Can’t wear it out in public.Really like the feel. Breathable. Shapes my already fabulous a** nicely. I am 5'6, and really curvy. 228 on a gooood day. I got the 3x. Could have gotten the 2x like I did for other pairs, but 3x has a little room to breathe, ya know.The fit of these are fine, the grey color is fine, it's the texture. I didn't think it would bug my skin, but I can feel the pattern on my legs, which is not comfortable. I don't like these at all because of it. If I could return them, I would, but they are worn so I'm stuck. This is not a fabric choice I will make again.These did exactly as they said! My birthday went from 51 to a 35 you’s!
