Princess Diana's wedding is still the standard by which all royal nuptials are judged by -- and even 30 years later, her dress is seen by many as the most memorable wedding gown of all time. Its 25-foot train, 10,000 mother-of-pearl sequins and acres of ivory satin are now making their way through the United States in an exhibition of 150 items belonging to the late princess. For fans in the American Midwest, it's the closest they can come to an icon, and also a way to celebrate the next royal wedding -- of Diana's son, Prince William, to Kate Middleton. A natural sound AFPTV report.
