Vintage Red Knit Midi Dress 100% Dupont-Orlon Acrylic Union Made Sz Small

This is a beautiful, super cool vintage cherry red knit dress. It is unbranded but has a label near the neck that reads 100% Dupont-Orlon Acrylic-Fibre. It has an open knit design and would need a slip under it. Perfect condition! Absolutely no flaws anywhere or funky smells. Zipper on the back works perfectly! No size label. My own flat lay measurements show its a SMALL/MEDIUM. **Please see measurements to ensure proper fit before purchase and to avoid returns:) I did find a Union Made tag and after some online researching, it seems as the tag dates between 1955-1963. I am not a vintage clothing expert, but just what I found using google. Flat Lay Measurements: Bust=35" Waist=29" Hips=38" Sleeve=6" Length=39" Shoulder to shoulder=14.5"
