Kate Middleton, the Duchess of Cambridge, celebrated her first official Trooping the Colour celebrations on Saturday in regal style along with her husband, Prince William and the rest of the royal family.

The 29-year-old looked stunning in an Alexander McQueen coat and black hat, matching the mood of the occasion. Prince William, on the other hand, was dressed in the red Irish Guards uniform he wore at his wedding along with a traditional bearskin hat.

A long-celebrated tradition Trooping the Colour has been observed every year by the British and the Commonwealth armies since the 17th century. Held every second Saturday in June, the event also marks the official birthday of the British Sovereign and involves a Royal Procession by the Queen. Following the Royal Salute, the different troops of the Household Division are then inspected by the Queen herself. This basically involves over 1,300 soldiers who parade past and salute the Queen.

One of the Foot Guards regiments is then selected to troop their colour through the ranks of guards. Following the Royal Procession, the Queen the led the Royal Family onto the Buckingham Palace balcony for the traditional Royal Air Force flypast.
