Cute Calico Sundress Girls Vintage 70s Dress Red & White Elastic Bodice flex fit

Super cute vintage seventies sundress in a red and white calico print. Fabric feels like cotton, fairly light weight. May be never worn, retains paper tag - says size 7. Label is RT Just Call Me RT. I would say hand wash & line dry. Condition is excellent, no stains, wear or damage. Length 39" +/- adjustable tie shoulder straps. Elastic chest 18-24", waist the same. Unusual find.
