Rare EUC Cop. Copine Paris wool petticoat size 40/S dark chocolate

This is a stunning wool coat. I can only find one or two more like it on the internet. The size is eu 40. Which equates to a US small. Please see the measurements. I took them while zipped up and laid flat. Armpit to armpit 20” Length: 32” Sleeves from shoulder down are 22” This is unlined, and the sleeves are silky material. I don’t know much about this jacket other than what I see when I google it. No rips holes tears or stains. Non smoking pet friendly house. Beautiful dark chocolate color. It is not black but it is almost black. Own a unique piece of Paris fashion!
