Vintage Hand Made Maxi Dress Lilac Sheer Puffy Sleeve Zipper Back

This vintage hand-made maxi dress in lilac color with sheer puffy sleeves and a zipper back exudes a Mod/GoGo look from the 1960s or 1970s. Made in the United States, I am guessing the fabric of the dress is made of polyester with a bit of spandex, but it does not have a tag because its homemade. I think it may be around a medium in todays sizing. It measures 19" across the front at the underarms. It measures 17" across the front at the waistline. Total length down the center of the back is 50". The sleeves are a sheer fabric with a puffy design and elastic at the ends of the sleeves. This original one of a kid piece of women's vintage clothing embodies the stylish and unique fashion trends of that era. Some of the gown is sewn and some of it is hand stitched.
