Vintage 90s My Michelle Raton Flouncy Floral Zip up Dress- Size S/M

Authentic 90s rayon zip up floral dress by My Michelle. Marked as a size 7/8, fits more like a 4/6, but please see measurements for best fit. I’m good vintage condition- there used to be a corset like tie at the back but it is missing, otherwise in great condition. (Taken flat) Armpit to armpit- 17 1/2” Waist- 15 1/2” Length- 31 1/2”
