I'm 5' 10", 150 pounds and 6 months pregnant, and a small fit me. It hits me above the knees. The straps are closer together than my bra straps, but I just tied the slip straps to my bra straps with nude thread to line them up. It's stretchy enough that I didn't have any problems. It's also stretched over my baby bump. I could probably wear this at 7 and 8 months pregnant.
