I bought this to add to my eclectic collection of "Party Style" Formal wear. I Like to wear these when I go the Opera, Ballet and sometimes "Broadway Shows."
I wore this with a cummerbund to the Ballet Last Night and several people stoped by my seat to offer compliments. A random waitress and mine also went out of their way to say something nice. This is not uncommon with many of my outfits but I think there were far more compliments for this than any other of my outfits all of which garner looks and compliments. I wasn't counting but I can recall 12 as I try and remember/count them now.
Why am going on about this? Well isn't that why You would buy this type of Jacket? To stand out and look good; Right?
As for size: I wear a 40-42 regular this was a Large and it fit perfectly. I am 5'11 and 175lbs, I could probably gain 10-20 pounds before it would stretch the button.
