Do you have a stash of bridesmaids dresses taking up precious closet space? NewlyMaid.com has a proposition—trade them in for LBDs! The new site, owned by formalwear manufacturer Dessy Group, offers you the opportunity to mail in your gently-worn bridesmaids frocks or prom gowns in exchange for discounts on six different styles of black dresses. Users request pre-paid envelopes, package up their used items, and send them to NewlyMaid, where they'll either be recycled or donated to the charity Clothes4Souls, WWD reports. The site then sends users an email with a discount code, allowing them to buy a new black Dessy Group dress at NewlyMaid.com. Discounts range from 30% to 50%, and all of the frocks are priced under $200. Would you use the service?
