1960's JEWELLED-NECKLINE GOWN WITH CAPE

This gorgeous gown unfortunately is tag-less and label-less so I don't have any info on it, except that I purchased it at Another Man's Treasure Vintage boutique in Jersey City Spring of 2010. They're a fabulous and well stocked vintage boutique that is on the higher end of the price range, but carry a lot of top designers and brands. There are 3 marks as shown, 2 smudge lines and 1 dot. I have no idea what they are or if they can come out, I never wore the dress. I think it would make a gorgeous prom dress for a vintage girlie or a fabulous Mother-of-The Bride gown for a formal wedding! Measurements - Armpit to Armpit 18 inches and Length 58 inches, no shoulders as the dress is sleeveless and the cape can stretch.
