Open up your lovin arms baby here I come - that is the feeling you get when putting your arms in to this beautiful coat so much luxury fabric in virgin wool, and then you do indeed want to spin right round in it it the fit and flare is so amazing.
It probably dates from the late 1980s early 1990s when brass button ornamentation came in to vogue with Lacroix & Versace, though this coat is by Rena Lange, German couture at its finest, and the buttons are stamped with their mark. 
 
The wool is quite long haired so very warm, and has a soft removeable sheared beaver collar. 
A size UK 10 or 12, this is a coat for life. The shoulder structure and tailoring are exquisite as are the buttons, and half belt for that enduring early 20th century military great coat feel, and shows no sign of ever being worn.
