Vintage 80's rare Sonia Rykiel Paris Velour striped dress. Size M/L

Cotton knit, gray and taupe signature striped velour, slight balloon silhouette long sleeved dress. Dropped shoulder, wide neck, back patch pockets, front side pockets, reversed (outside visible)hems, Ribbing at collar cuffs and sleeves. Pullover style with slight stretch. Made in France. Length: 34" armpit to armpit: 24.5" shoulder to shoulder: 22" sleeve: 25" * Size and material tag have been removed. Since this is a vintage designer piece the size is a guess based on how it fits me. ( I am a size 6/medium and it fits me perfectly with a relaxed fit, so could fit a large/size 8/10) * some small pilling throughout. * hard to see small "scratch" on front near collar. But otherwise very good vintage condition.
