Vintage Starlight flapper dress - costume

I bought this on Etsy to wear to a costume party. there are some missing beads but they were missing beads when I bought it. it's extremely heavy. I wear a size 12 and I thought it was too big for me but I went ahead and wore it because I didn't have time to get a different one. I got a lot of compliments on this because it's authentic looking. I know the tag says Large but I'm putting it as size 14 because of how it fit me
