Uniqlo U Wool-blend Long Peacoat, Blue/Grey - Tagged XS but best fits S/M

Uniqlo U Wool-blend Long Peacoat, Blue/Grey - XS FW 19, designed by Christophe Lemaire Very good condition, worn very little and not in years. There is one missing button behind one of the lapels (see video), and the string holding the buttons to the coat could use reinforcement. Marked as XS but would be best for a medium or small, depending on desired fit. All around beautiful coat, reminds me of Madeline
