I've been meaning to share images of this incredible Qing dynasty dress from a family friend's collection for a long time but have not gotten around to doing it... Apart from the profusion of embroidery motifs, the copper red background fabric, somewhat transparent and loosely woven with a pattern, also seems like a kind of fabric that has been lost in time. I am not sure but I would think the dress belonged to a Manchurian noble woman in the 19th century. Below I share images of the dress and some historical photos showing women wearing its like.
