Never doubt your fellow reviewers when there is concurrence, like I did.  I had to return it because - yes - it is too big.
As other reviewers mentioned, this is an overcoat, sized assuming you will be wearing a suit or sport jacket underneath, but it's still too big.
The coat itself is pretty nice if a bit thinner than my previous wool coat.  It is mostly too big around the shoulders and chest. I should note I don't have a big chest or shoulders, but normally I do fine with a 40 Reg overcoat. The sleeve length was just right for me, if a little short.

I get this warm fuzzing feeling shopping at Amazon - it was free to ship and free to return. Double check on the free return  before you buy because they do change this.
