“I really liked this sports bra because of the style. I am usually a size Medium in mostly all tops, sometimes a small, however I do have a wider upper back (I have wide lats), so this bra, I got a Medium and it is slightly tight around that area. the fabric doesn't have as much give as the other training bra. I still love this top, regardless! but if your built a little wider up top, I may recommend possibly a size bigger.”
