Vintage tea-length strapless Gunne Sax prom evening dress by Jessica McClintock!! It’s satin fabric with a lace appliqué down the center front bodice. There’s crinoline underneath for structure. The tag says 3, but this would probably best fit a size XS. (Measurements lying flat: Bust - 13” & Waist - 11”) There are a few small white spots and two small snags on the front skirt (shown in photos.) They’re hardly noticeable now, but the spots could probably be hidden with a little magic marker 🙊
