This is a fabulously stylish & almost immaculate fitted Canadian coat Sanders & Gold of Montreal.
THe cut and structure of the coat is stunning and details exquisite. Probably dates from the early 1990s. The collar is black fox fur.  A UK size 10 though a small 12 would get away with it. 
Hidden button fastening for a very chic line, fit and flare, lovely half belt detail and vent on the back. It's beautiful and almost immaculate but for two small marks probably historic moth damage, barely noticeable not bad damage. However I have reduced the price by £200.
