This Vintage Jessica McClintock Gunne Sax Dress is in Excellent Vintage Condition. It doesn't have any stains or wear. The fabric is blue velvet and a natural color cotton fabric. It has lots of interesting string like lace details and a self tie on the front. The blue velvet panels on the sleeves is interesting. There is a zipper in back that works nicely. The dress has the Jessica McClintock tag but the size tag is gone. However, by the way it fits my mannequin it is most likely a Small but may fit a medium as well. So, be sure to check my measurements below. This dress is a classic. Thanks for looking.
