Super tight fitting
I usually fit into a size small so I ordered S/M. (I'm 5'2, wt. 130 lbs.) If you have any "fat rolls" on your back you can definitely see it! I was assuming it would flatten my fat out but does not do the trick. Definitely size up! Love the color though.
Rated -1 on a scale of minus 2 to 2, where minus 2 is Too Small, 0 is True to Size and 2 is Too Large
