As ever, the Germans bring a characteristically irrefutable logic to bear on this thorny problem. One can easily find a fur hat to wear to the head warm, but fur trousers are less commonly available.
Glad you liked it. Do so at your own risk! :)
Seriously though, I'm happy with how the shoes, jacket, shirt and tie worked. Trousers were OK. I think the waistcoat colour was right, though it would look better if it fit a little better and was cut a little differently.
