Beautiful Custom Crystal Party Dress

This is a hand sewn vintage dress with beautiful details and gorgeous crystals. I am not sure who the designerIt is a size 4 womens gown. I am unsure who the designer is, which is a shame. I see gowns that are similar online, but they are reproductions. This is an original vintage gown that I purchased awhile back at a store in Beverly Hills where they sell clothing that is worn by the stars in movies and award shows. They were unable to get it authenticated, but is is believed to have belonged to Marilyn Monroe. It is breath taking and just may be worth a lot of money if you are good at research and can find who it belonged to.
