XS/S navy blue sparkly prom dress

Edit: I will only communicate though Poshmark, NOT email It is navy blue, floor length, has mesh covering the cleavage, three straps to hold the open back, and very glittery. Original price was $799. I usually wear S/M, but this is advertised as XS. waist size 26, and I am 5’3” with 3” heels (touched the floor). Worn only once.
