Vintage black maxi coat NWOT

Vintage black maxi coat. NWOT. Perfect condition. One button closure. 24.5 inch back slit at bottom. Shoulder pads. Satin trim. Notched collar. Slash pockets. Princess seaming front and back. I am the original owner. It has no tags in it, so go by the measurements. This coat is absolutely beautiful!!! Back shoulder to shoulder 17 inches Hips 41 inches There really isn’t any fit across the bust. Length 52 inches Underarm across the back is 24 inches. It really does not wrinkle; I would say it needs to be dry cleaned( not washed) ; Not now, but if you get it dirty.
