I was a little hesitant buying this type of legging (booty scrunch) but I really do like them! I am 5’5” and weigh 160lbs and typically wear a size 8 and I purchased a medium. These fit awesome. I think if I get anted to go a size down, I’d be able to get into them, just depends how compressive you want them to be. The fabric is a little thicker on these and they are definitely stretchy, so no worrying about if they are squat proof. They have a high waist and don’t fall down.
