George Gross Vintage sz 12 Floral strapless Lace Top and Cardigan Set Beaded EUC

Elegant floral lace beaded top with matching cardigan. Rich red and gold tones. Evening Formal. The one side of the cardigan is longer than the other. I’m struggling to figure out how this should be worn. It does not appear. The shorter side was cut so I am confident it was made this way. Pictures do not do this justice. It is absolutely gorgeous.
