William's Irish Guards uniform has the distinctive button arrangement of the Irish Guards.
William paired his uniform with the Order of the Garter sash, the Queen's Golden Jubilee medal, and his Royal Air Force wings.
William's younger brother Harry said he was "gloomy" and "frustrated" about wearing the uniform on his wedding day.
William reportedly asked to wear the cavalry uniform and frock coat of the Royal Guard for his wedding.
William knew that it was for the best and accepted the Queen's decision.
