I just received this today in Alabama on a Friday and ordered it on Tuesday and it came all the way from Scotland! Wow! I normally wear a 46 L and after reading the reviews I listened and ordered one size up, a 48 L and it fits absolutely 100% perfect! Im so glad I did this my usual 46 L would definitely be too tight! I really believe the sizes in America are screwed up and just said to be smaller than they actually are. Love the quality of this jacket and waist coat and it even came with some replacement buttons. I cant wait to wear this to my next formal event. If you're considering ordering this and live in the US go ahead and order one size up from what you wear.
