The label has been removed from this vintage bra so I don’t know the maker. My guess on the size is 36B or C. The one piece overwire design was popular in the 1950’s. The stiff wire is one piece going over the top of both cups and dipping down to a low plunging gore. There is thick padding on both ends of the wire for comfort. The two section cups are unlined with sheer lace on top and shiny satin below. Fastens in back with three hooks and two positions. A sheer mesh ruffle circles around the top of each cup. The bra is in good condition for it’s age except for some stretching of the powernet wings.
