Hi friends, I bought this black evening gown (late 1930s, early 1940s I think) which has a faux wrap front. The wrap piece that would be hidden from view has a gap with two hook and eye fastenings. It doesn't look like a mend or damage and appears to be an original part of the dress. I could be wrong on this. Anyway, has anyone else seen this feature before or know what it's purpose it. Cheers!
