Rare original Bernetti New York vintage dress

My grandmother wore this rare vintage original Bernetti NY dress to my dads wedding. I don’t think anyone else has ever worn it. There’s no size but it’s about a 2 or 4. I haven’t tried cleaning it, I pointed out the marks in the pics. This dress is so flattering and so expertly made. The flap in the back makes it look like you’re wearing wings. I would model it but it doesn’t zip on me anymore. I’m 5’3” and the dress is a couple inches above my ankles. It looks so cool.
