I''ve been looking for something that is stylish for the gym. I am 5''8", 150 pounds and the medium fits well. A lot of your back is exposed so its sexy! but not in a vulgar way. I originally had wanted a top from another popular yogawear chain but I have some ethical reasons about not supporting them, the clothes are outrageously expensive and the tops that come in this shape  are forever sold out anyway. Also with this top, there is no built in bra as with many tops in a similar style have. I have a large bust and a small ribcage so no top with a built-in bra would work for me. I love this top!
