"these are cute in the picture, but when i tried them on after i got them in the mail, they were a little diaper-y on me. Of course i know that's how they are supposed to be, but they draped really badly. This might be due to the fact that they came wrinkled, so hopefully they will drape better when i iron them. As for sizing, i bought an xs. i am 5'7'' 115 lbs and they were almost perfect, but almost too loose, which surprised me, due to the fact that I'm usually a small. so size down, maybe? unless you have a booty, which i dont. : )"
