So I got this in small without checking the size measurements. When I decided to do this review I checked the sizes on the side since lately some size small on amazon run like a medium I guess depending on the company and if it is juniors or not.  Small for this top is (0-2). Mind you to me size small is (4-6) so that is why I ordered it. LOL and it fits great . I am 5'2 135-140 lbs. 34C . So I am guessing the size chart is off. Basically if you are a lady who always wears a size small (4-6) this top will fit you. Enjoy!
