If a $250 wedding gown from Filenes Basement “Running of the Brides” is not a cheap wedding dress in your mind, try eBay you never know what you will find. One bride purchased a simple but elegant sheath gown for $27 with one other bidder as a competitor. The gown had been purchased from Sak’s Off 5^th Outlet and the bride didn’t lose enough weight in time for the wedding.
