Shiny, teal prom dress

Shiny, teal prom dress with halter v-neck covered in beading. Back is open with bead-decorated mesh bottom. Ruched around the bum area. Worn once by a 5'2" girl wearing 3inch heels and a 32A bust (cups sewn in) very slight stain as seen in picture. We never attempted to get it out so it may not be too late, but it's barely noticeable
