Exceptional piece - exquisite attention to detail.
Can be worn as a duster coat, night gown or you could belt it and wear it as a dress.
Note that it is very long - best suited to those who are 5'8" or taller (or you'd need to be comfortable with it trailing on the ground)
Hand painted, with embroidery and beading in places.
Excellent vintage condition - a few very minor marks here and there. Also a mark on the back internal lining near the hem (see photo).
