This is truly a one of a kind gown from the 30's. The label reads "Registered by a member of the Fashion Originators Guild" Made of Quilted rayon. Classic 30s halter style with gathering at the center of the bust. Bias cut. Sweep train. Comes with a matching belt. I did not find any flaws. Best fit would be a S/M, however, please see the measurements below for a proper fit.
