eBay, flea market, garage sale, or you can donate it to Goodwill or the Salvation Army. Just a thought as a joke donate it to a charity which sends clothes to third world nations and they can gather up all the old prom dresses and have all the women or girls in Central America, the Middle East, or war torn areas of the world look as if they are waiting for a Limousine to pick them up for their prom! :-) Wouldn't that look funny in a small village in Honduras all the women between the ages of 17 to 25 wearing old American prom dresses? Thats a hoot and a funny one at that. A scene right out of one of Charlie Sheens comdey films of the 1990's.
