Open Back Beaded Evening Gown

Only worn once, in terrific condition. No flaws that I could find. Has molded cups and is fully lined. Probably fits an A or B cup best. (That’s me in the photos and my bust is 34A, waist 27/28”.) Measures 16” from armpit to armpit. 58” long from shoulder to hem. Knit poly fabric. Originally purchased from Macy’s.
