Top was too big and bottom was too small. Not stretchy enough but still very flattering.

I'm 5'3", 135lbs. The top was too big, and actually doesn't come with true straps to hold the top up - the "sleeves" are the over the should cap (I have to sew on straps) nd the bottom was too small on my bum. I would say the top fits more like a M and the bottoms like a S.
