Vintage Purple Women’s Size M Long Dress 1970’s

I LOVE this dress! It’s in excellent condition despite being from the 1970’s. Women’s size M but it seems to run small so please pay attention to the measurements to be sure. It was my grandmother’s who was a super fancy, elegant gal who had excellent taste in clothing! It’s too small for me else I would keep this beauty. Length: 52” Bust: about 27” Waist: about 28” I believe it’s cotton (not entirely sure) so there’s a little stretch to it, but not much. Thank you & enjoy!
