Would like to ask group on how my Fivestar HH Dubow fits. My chest measures 43. The L/44 was too tight zipped up. I had to return it and go up one size XL/46. I had t-shirt on in this photo. My concern if I go up to 2XL/48 it might look oversized but will accommodate layering. From the forums the A2 is a more form fitting jacket. Welcome your replies on fitting and if going up to size 2XL/48 will be too large on me. I very impressed with the jacket.
