Floral Blue and Green Sleeveless Dress

Groovy actual sixties floral dress with a zipper back. Was long when originally purchased, but I hemmed it short to be a Cocktail dress. Some approximate measurements: Nineteen inches pet to pet Thirty two inches from callar to bottom No size markings whatsoever but fits like a large, with lots of darts for potential alterations. This item has no tags so I wouldn't be surprised if it was homemade from a pattern in the sixties. So cute!
