Vintage Alfred Angelo Prom Dress

Incredible vintage Alfred Angelo prom dress! Puff sleeve, sweetheart neckline, open back with bow across top, high-low look. Cannot find size tag, but it fits like an XXS-XS. For reference, I am a size 2-4 dress and it won’t zip all the way on me. Iridescent dark blue color. Approximate measurements: 16" underarm to underarm, 13" at waist max, hips open, length in front 49", length in back about 57".
