Twenty-six-year-old Prince Harry was chosen as best man despite being unmarried. (Traditionally, a best man is already wed.) Perhaps because of his bachelor status, Harry received louder cheers than William when greeting the crowd.

Harry arrived with girlfriend Chelsy Davy, however, who wore an aqua green bias reverse satin short dress with a silk jacket to the ceremony. The 25-year-old Zimbabwe-born blond will change into a one-shoulder midnight blue crepe satin gown with a cutout detail on the back for the evening party.

Harry is hosting an all-night party Friday evening for the royal couple and their friends. He has reportedly turned three rooms at Buckingham Palace into a nightclub for VIP guests. A DJ will play into the early hours, and caterers have been briefed to prepare bacon sandwiches and fry-ups (a dish made up of different fried foods, usually eggs and meats) for the wee hours of the morning.
