Elizabeth Taylor is no stranger to weddings, and decided to break tradition for her fifth walk down the aisle. She wore this sheer yellow gown with flowers in her hair. Only Liz Taylor could make that headdress look so effortlessly beautiful.
Quite possibly the wedding of the century, Princess Diana wore an equally larger-than-life dress to her wedding to Prince Charles (hey, it was the 80s). The train is 25 feet long, the longest in Royal wedding history.
