Chest measures 52” but I think realistically it’s a 14/16/18 as the arm hole is 17inches around. The lining doesn’t go down the arms so not really fully reversible , pockets are on the inside. Lined with  lovely pomegranate coloured vintage fabric, jacket made from a vintage American hand sewn quilt. Length from shoulder down 23” . I haven’t added any closure but that can be added if required.
