RL, pretty sure I got the same coat at last summer's NAS, in an emerald green color. If it's the same one, it's not a fitted cut in any way. It kind of flares out behind, and the collar is big and blanket-y. (Stunning lining, thought, right? I'm a total sucker for a beautiful lining.)
I wore it to a sunset wedding that was held in the woods (literally) in upstate New York in October. As soon as the sun went down, it was 40 degrees outside and I was so glad to have that coat with me!
