Absolutely stunning, "one of a kind", vintage formal by Jessica McClintock for Gunne Sax, size 5 junior. This beautiful gown is strapless, fitted, with a boned top. Poly/spandex fabric. Eggshell background with navy pattern, reminds me of Blue Willow antique porcelain. Back zipper and hook. I love how the skirt dips slightly longer in the very back to form a short train. YOU WILL BE NOTICED in this dress! So different and special! Can even be machine washed. Approx 15" across the chest with a little more fullness in bust. Approx 13" across waist; approx 18" across hips. About a modern size 2/4 (a tiny smaller in top than bottom). EUC; no flaws found except very tiny fuzz along bottom edge of hem; no stains, but I have not laundered Ask. No lowballs, please. Prom, homecoming, bridesmaid, wedding.
