IRISH media covering the wedding from St. Margaret's Church were very, very excited that William wore an Irish Guards Mounted Officers' uniform in Guard of Honour Order with a Forage Cap. He wore a gold and crimson sash and gold sword slings, but he did not wear a sword. He also wore the Garter Sash with the Wings of the Royal Air Force, the Garter Star and the Golden Jubilee Medal.
The tunic is Guard's Red and features buttons sporting the Harp of Ireland with the Crown Imperial.
The Insignia of the Irish Guards on the Forage Cap is an eight-pointed Star of the Most Illustrious Order of St. Patrick and features the regiment's motto 'Quiz Separabit?' (Who Shall Separate Us?).
Among the titles given on Friday morning to Prince William, who will officially be known as the Duke of Cambridge, was Baron Carrickfergus, an ancient title connected to the site of Carrickfergus Castle, which dates from circa 1180, and is considered one of the best-preserved castles in Ireland.
William is now also the Earl of Strathearn, giving him a connection to Scotland. Among famous dukes of Strathearn were Queen Victoria's father and her third son. The title had been extinct since 1943.
Prince Harry wore a Blues and Royals officer's uniform in Dismounted Review Order, with a Forage Cap. He wore aiguillettes, a cross belt and a gold waist belt with sword slings, but, like his brother, no sword.
He wore the Wings of the Army Air Corps and Golden Jubilee, and Campaign medals from Afghanistan, where he served.
The Forage Cap carries the badge of the Blues and Royals, which features the insignia of the Most Noble Order of the Garter with the Queen's cipher.
Harry is known to have a colourful personality in the Royal Family. He looked back at Kate coming down the aisle, while William did not turn around. Lip-readers said they believed Harry said, "Wait till you see her," and made Wills laugh.
William had to struggle to get the wedding ring on Kate's hand, which led to laughter in the Abbey and nearby St. Margaret's church. He is not going to wear a wedding ring.
