VTG Early 70s Gunne Sax Halter Maxi Dress M Blue Floral+Lace Cottage core Black label

VTG Early 70s Gunne Sax by Jessica Halter Maxi Dress M Blue Floral+Lace Cottage Core Hippie-very good used condition, with a couple of tiny light stains as shown...the long front lace panel is darker ivory and I do not know if it will whiten up.
This is one of the rare early labels by Jessica McClintock. The label indicates 1969 or 1970.
It ties at the neck and has a back nylon zipper.
