Hi All, I recently came across a dress and I'm trying to date it. There's a size label - 38 (although in modern sizes it's definitely a small 36 EU) and no other labels. There's overlock, but I would call it "simple". Bottom hem hand stitched. There's no fabric label, but it's a rather stiff cotton. Model in the picture is 171 cm tall (5'7). My guess is late 50s / early 60s but I'm really not sure. What's annoying me the most is that I have trouble finding pictures of vintage RIES zippers and those I found look nothing like mine... Thank you for any help!
