Rare. Retired, Betsey Johnson Evening Dress

My prom dress from over 10 years ago, I’ve held on to it but have finally decided I don’t need it any longer. Light blue tulle with iridescent shift. Underlining is baby pink and the middle part around the just us more of a salmon pink. Size 2, definitely true to size. Knee length on me, and I’m 5’1”. Strapless with corset style bust so it stays put. Zip back. Purchased from Betsy Johnson store back when they still existed. The minor flaw in 3rd pic is just the stitching, can’t be seen from afar
