Real leather coat with detachable faux fur collar - muted dark purple (see last photo to show comparison with black) -  vintage - FABIANI.  Label size 40 but this would be a massively oversized. I'd say a very oversized retro UK 16 but still roomy on a UK 18. 24" pit to pit. 33" length. 19" shoulder to shoulder. 25" shoulder to cuff. Dry clean only. Not far off new.
