They run way to small!. I'm about 5"5; curvy, large hips and thighs, and i ordered the Large (which is what I normally wear in sweats) and they barely fit my legs and my waist, and tend to slip off my bottom when I roll to the floor after a jump. RUN Too SMALL.
These are very comfortable and cute to wear! I wear them all the time! I am going to order a second pair just to have on hand because I like them so much :) I try not to dry them to keep the lettering nice but I have forgot a few times and they look great.
