Vintage night gown- 60s? 70s?

This night dress was given to my mom by her older sister and then given to me by my mom. It is absolutely a statement piece. You could wear this out as a dress for sure because it’s not see through. There are no original tags on this garment so it is impossible to know what size it is or how old it is exactly but definitely pre-80s from what i can tell. I believe it’s a medium? It fits me well i am 6’0 and 160lbs, but on a shorter person it would be ankle length instead of midi. Check out my closet for more rare/vintage items!
