First off, this dress is so niceley constructed, you’ll know it’s a quality piece. The back seam is separating & fraying as shown because it was worn by a person that was 2 sizes too large for this piece. No size or material labels left. The maker label says “Perri” Montreal. TRUE VINTAGE 1960’s Blast from the past dress!! I took measurements of the dress laying flat, on one side. Material is a substantial weight woven linen-type. Rear metal zipper. B: 16”, W: 14”, H: free. Length is 30”. Couple issues.. the rear vertical fraying seam already mentioned. Inner lining a bit off color. Front now has some loose stitches. And the hem is not professionally done, but it holds ;)
