Vintage night gown

The absolute most beautiful vintage night gown. I covet this thing... I wish it fit. Early 60's for sure. Normal Vintage wear. No big flaws that I can see. A couple small stains on the back. I have never tried to get them out. Flowey and gorgeous. This fit a bit snug when I was a size 12. I am listing as a Medium. A small to med would be best or a large with smaller chest.
