Party Dress Mid Century Vintage Handmade Sleeveless

Handmade vintage dress. Metal zipper in the back. The dress is lined with a nylon fabric. There is no size tag as it's handmade. The bust measures 26" and the waist is 24". The dress is likely from the 50's or 60's. I'm unsure of the type of fabric it's made from. Someone suggested it's silk but there is no tag. This dress is simply beautiful. The dress is long enough to cover the knees which met the school code of the 50's and 60's.
