Antique Polka Dotted Dress

Antique vintage 40s/50s Thin raw silk grey and antique white polka dot Super full flowie skirt Top is lined with an unusual material not sure what it is but I imagine it’s supposed to be like boning … help giving it structure… It’s in great condition… I don’t notice a flaw to report Super classic Pics serve as part of description Labels says sz 12 Seems like a modern M maybe S/M with that little waist —/ please check measurements there is no stretch …
