Vintage Best & Co. black faux fur coat.

My grandmother got it at an estate sale yeeaars ago but it didn’t fit us. I did some research and the company closed in 1970s in NY. It’s unbelievably soft with plum silk lining. Price is based on similar eBay ad. Feel free to ask questions. I can’t find the size but it’s anywhere between M-L. Length from shoulder is 40in, armpit to armpit 25in buttoned closed and 27in waist also closed.
