Prom dresses

Both were worn literally one time (as seen in the picture) for literally four hours max. There are no damages, stains or anything caused to these dresses. I’m just looking to get rid of them because I haven’t used them in two years and they’re obviously worth something. The purple one is a size 6 and the beige one is a size 8. Price is firm. Asking $225 for both together or $150 each separate.
