White and gold prom or wedding dress

White and gold prom or wedding dress. Strapless Size 4/6 Worn once for a prom, and is a little “discolored” along the bottom from being worn. It will come out with some bleach, stain remover, or dish soap probably. Also would best fit a C or bigger cup but could be altered. Floor length on a 5’5” woman I paid $200 and only wore it once so I’m asking for at the very least $150. From a smoke free not pet free home
