So comfy and easy to wear. I\'m 5\'2 140 lbs and I bought a medium... At first I thought I probably could\'ve gotten the small because it was a little long in the legs and a little roomy under my arms, but it shrank a little the first time I dried it and now it\'s perfect. The drawstring is only decoration but the elastic waist is nice and snug (but not too snug) so it stays in place just fine. Love it so much that I ordered another.
