Antique 1920’s Silk beaded flapper dress

I have owned this beautiful dress 30+ years and have kept it rolled up in a silk pillowcase it has no label but has a tag with 40 on it so think it is a European size and I would say it is a medium size 8/10 US I acquired this from a very wealthy elderly client’s estate It has a silk slip under it There are a few spots where the beads are loose and a few pinhole spots on the fabric but for a dress that is 100 years old it is pretty much museum quality It is a treasure!
