NYE style Metallic silver beaded formal dress

Gorgeous dark grey beaded cocktail dress (flapper style) with geometric beading pattern. Dress has narrow shoulder straps (~1” wide) and an overlapping top tier that connects directly to a knee length lower portion. It’s one piece as a dress but the top portion overlaps the lower. Heavy beading make this dress weigh nearly a pound. Purchased for a NYE gala but never worn. Is RED sub-brand by Saks Fifth Avenue.
