Vintage 60's purple, blue and green floral nylon shift dress

This vintage 1960's pastel print sleeveless shift dress has a darted bust, a pretty straight style that sits below the knee, a back zipper closure and is fully lined. Tag states size 12 but I would say more of a size 8. Measurements Shoulder to Shoulder: 15" Chest: 36" Waist: 33" Hips: 36" Length: 38.5" Zipper: 18"
