Extremely Rare Vintage Comme Des Garcons Dress/Skirt

This is an extremely rare Comme des Garcons dress or skirt I bought from the Comme des Garcons store in Soho, NYC in the early 1980's. It can be worn as a strapless dress, with the flap tied in the back, or a skirt; as shown in the pictures. A very light weight, silky feel and a warm black color. Size M, button closure (they can be moved to adjust) The color is very dark midnight blue.
