Labelking, My tailor was able to do this, but it did throw off the ballance of the coat a bit. He said normally they can only alter the chest size down a half-size to a size (42 down to 41.5 or 41). He was able to take two very nice jackets I had purchased down from a 44 to a 40. Basically, he had to open the entire back seam (cut the coat in half) and trim the material...overall though it doesn't look half-bad. I think he might have given me a very discount rate but he charged me $70 to have both jackets taken down, plus to have the waist taken in and the sleeves shortened, and one pair of pants adjusted in the waist. Not a bad deal.
