Does not fit like photo

I loved how this top looked on the model, but on me it was uncomfortably tight in the ab area. I don't have a six-pack but nor am I fat - I'm 5'2" and 102lbs. The shape basically tapers down instead of appearing straight. I exchanged for another top but it still had the same issue. The shoulders fit fine though. Gorgeous fabric. Too bad, I really wanted this one to work.
