I like the coat, but I am not totally sold on it, given the price point. The zipper is definitely polarizing and perhaps too trendy. I would not want to go trendy on an investment piece, at this "up there" price point. Will you bore of the zipper down the line?
My other issue is that the flaps seem to be laying funny at the bottom, see picture #7, it could be the photo, but they are not perfectly aligned. The puff makes them rise up, ah, not as sharp as they could be. I also wished they had gone either full force with the diamond shaped quilting or just gone with the horizontal seaming. I find the diamond shaped quilting a bit ALGO given the zipper, buttons, and seaming.
I think Burberry would offer free alterations, so the sleeve is definitely not a deal breaker to me.
Had this been a $100 coat, I'll be all over it. I think it is a fun coat to have, and it totally jives with your style. I just expect a certain level of "perfection" at this price point, but if you love it, keep it. God knows than when I fall hard for something, I just do what I want.
