Vintage 70s Gunne Sax by Jessica McClintoc Prairie Mini Dress Size 9 Cottagecore

Gorgeous true vintage piece for collectors and lovers of 1970s fashion. This cream prairie mini dress is a standout from the Gunne Sax era, likely early Jessica McClintock based on the RN 40527 and construction style. The squared neckline and cuffs are trimmed with vibrant rainbow geometric embroidery—classic details that define the romantic, boho aesthetic of the time.
This is the kind of piece you rarely see in this condition. It has that soft feminine structure that Gunne Sax fans chase: puffed sleeves, an empire waist, gathered bust, and flowy skirt. Lightweight, no-stretch fabric, most likely a 70s poly blend. Labeled a vintage size 9, fits like a modern Small.
* The style number 5600 and cut 6574 format also matches known Gunne Sax tag layouts from the late 1960s to early 1970s.
* The embroidery and peasant dress silhouette are hallmark Gunne Sax design details from that era.
