New peacoat looks great. Only things I can add, really, based on trying on the old one: Keep the collar and lapels as big as you can, as I think that really works well with the look. And the buttons on the other one were sewn right threw all layers, meaning it cut down on the hand warmer pocket space, as the sewing cut off parts of the pocket.
Any idea on what the rough final length might be on a large? I'm hoping I can still cover a suit jacket with this thing.
