I have bought the jacket in the photos. I am getting the sleeves shortened and the waist let out so there is no x around the button and the jacket does not flare out below the button. The jacket seems to fit well in the chest and shoulder area from the front. But there is a noticeable downward sloping divot on the shoulder when viewed from the side. There appears to be excess fabric near the arm hole which is somehow not visible from the front. What might be causing this and how can it be resolved?
