VNTG Caron of Chicago 80's midi dress Made in USA

Cute Caron of Chicago vintage dress. It has an elastic waist. I do not see a tag which tells the material however I think it is a polyester blend. Tags put this from 70s to 80s. Tag is a vintage size 12 but please check the measurements. Measurements: * Length measured from top of shoulder near near neck to bottom 41" * Length from shoulder to waist 15-1/4" * Across the Chest 19" * Across waist unstretched 16.5" * Sleeve length measured from underarm to end 8"
