I ordered a med/large because I've got curves and I didn't want to be too small.  It ended up being a tiny bit bigger than I liked.  Wish I'd gotten small so it could be super tight but I can definately make do since I'm just being picky. The material is feels soft, durable and strecthy...I have large calfs so I would know if it can streatch and it can :).  I'm gonna give my measurements cause thats what I appreciate most about clothen reviews. Its so helpful to know the body type of the person.  I'm 5'4 180lbs w/thick thights, a lot of booty & 34D. I normall wear a size 12 pants & Medium Tops and in dresses I'm a sz8.
