Danier brown leather jacket size 2XS (fits big, like an XS/S IMO)

I was never an XXS in any other item but this fit me when I was an XS/S Gorgeous jacket, just does not fit anymore!! The button on the top right shoulder is gone, could easily get one put on/ put one on yourself :) one loose string on right pocket as well (easy fixes I would think (see photos)- priced accordingly!) 15.5 across bottom of jacket and 17-17.5 pit to put as shown in photos, length from top to bottom of jacket approx 24 inches NS NP home
