Leggings are so hard to size. My wife gave me a couple of pair she didn't like, and they are a little baggy on me, they are XL. I bought some cute ones from a local store the same color as these (lavender) and they are size large and fit well/ better. They are not scrunch butt, but they still look sexy.So, I bought large in this style because I wanted a pair that has scrunch butt. I love them so much because they give me a nice feminine peachy butt and they feel great. I think the stitched part is a little high so it doesn't stay in my butt crack the way I would like, but I still love them. They fit well other than maybe a little short in the legs. I don't mind that because I often pull my leggings up to have a caprice look anyway.I love the color, it is just beautiful. Maybe after I wash them, they will fit a little different. If so, I will return and edit my review. My wife says they look good on me, but I can't wait to wear them to my friend's house this Friday, he will be the ultimate judge. I say, buy and stick with normal sizing. They do stretch nicely, just the scrunch doesn't stretch at all. I don't wear panties with them, but they are thin enough that they will show through. If you like to wear panites under leggings, should probably use a thong or no-show panties. Go buy!!! Seriously.
