Vintage 60s hostess fit and flare dress. Turquoise and green three-quarter length sleeve and scoop back. No tags in this dress other than a lot number tag on the inside back zip closure with a metal Elem zipper. There is no fabric content tag, but I would not be surprised if this is silk. Lay flat measures 40 inches shoulder to him, 17 inches armpit to armpit and 13 inches straight across the waist. There are a couple of stitches on the underside of one of the arm seams. See pics. Based on the measurements above, I estimate this to be roughly a modern size 4, but please double check to ensure the proper fit for you. It is featured on a size medium dress form and although it fits, it is snug.
