For reference, I'm 5'8", 190 lbs, 40D and I'm wearing an X-Large. So far, this appears to be a well-made, fully-lined blazer that, out of the package, was pretty wrinkled, but after a quick cold wash/line dry and a little steaming, it was good to go,and it's a perfectly solid blazer that will be a good addition to my wardrobe.
