Contourwear runs small. The body conscious fit can be very sexy, maybe too much for some. The measurements on the size chart are for a close fit, but not snug. The fabric of this top is clingy. You may want to try a bigger size. Backcountry.com has a great return policy.
I have this top in size small in black and wine. My shoulders are 38" and 35.5" bust. I would have tried on the medium if that were easy, but the small fits very nicely. The medium might have had room for a light layer underneath.
This top falls at mid-hip on me. I am 5'8" and 125#. This is not my favorite top because I have not found the right jacket to layer over it. It is comfy and has a lot of style.
