I wouldn't recommend the proper blazer - navy. It just didn't fit right.
I'm 6"2" tall, 83kgs, 41 inch chest, 35 inch chest. I tried the 42R and 40R in tailored fit. Both looked horrible on me. Too much excess material around the waist and it made me look like I had "fat man arms".
Unless your a beer bellied American, I'd try something else.

I bought this to replace my previous proper blazer, which has lasted for years but is starting to look a little beaten up. This new one is a great update. I discovered that I can wear the short fitting, which fits me a bit better than the regular, and looks better on me. This blazer has patch pockets and contrasting buttons, which look good. The jacket has has a strong and robust feel about it while still being comfortable. Its less formal than a suit jacket but still smart enough for the office.
