You should be fine though I would suggest at your size maybe getting the back pleat stitched the full length of the shirt. My chest fluctuates between 40-41 and a Medium fits me fine. For the premium collection does anyone know for sure if the stores in NY have the cropped pants? I need those and like WhoKnewI that stuff reminds me of last spring/summer +J collection. Thinking of picking up cropped pants in navy and black with regular navy pants and the navy blazer to put together a cheap suit for summer weddings.
