Photographs from Prince William's wedding to his university girlfriend Kate Middleton are some of the most famous of the decade. The beautiful bride's perfect Alexandra McQueen dress looked stunning against the groom's bright red military uniform.
But according to Prince Harry's memoir Spare, William actually wanted to wear something different for his big day - but his grandmother the Queen rejected his request.
It's traditional for members of the royal family to wear military uniform on their wedding day, and the Prince of Wales originally opted for his Household Cavalry frock coat uniform. He joined the Blues and Royals as an Army Officer in December 2006 after a 44-week training course. A year later he was promoted to Lieutenant and he remained in the unit until he became a Search and Rescue pilot in 2009.
