Hello and thank you for the accept. I am very new to vintage , so i would like to apologize if i start this identification journey with all you experts here, with a not so vintage apparel today. At first, thought it was a house coat, but weights over a kilo! The only label has, is the one i took on photo. Is made of rayon, both shell and lining. I searched a lot on net, to find something similar, but no success. Thank you in advance. Any suggestions to helpful articles about vintage fashion would be appreciated.
