The Duke and Duchess of Cambridge joined the 1st Battalion Irish Guards at Cavalry Barracks in Hounslow today for the annual St. Patrick's Day parade.
Kate presented shamrocks to members of the regiment.
The Duchess also gave one to the Irish Guards mascot, Domhnall - an Irish wolfhound.
Kate was on point in a new custom green Alexander McQueen coat based off a military jacket from the designer's ready-to-wear collection. Thanks to @LadyParky79 for the information.
Here's a look at the back of the coat with peplum detail. It gives the illusion of separates.
The Duchess also donned a new hat, however the milliner is unknown.
We saw the return of the Cornelia James 'Imogen' Black Merino Wool Glove.
Kate wore her dazzling Kiki McDonough 'Special Edition' Green Tourmaline, Green Amethyst and Diamond Earrings.
The look wouldn't be complete without the gold three-leaf shamrock brooch, pinned just above her sprig of shamrock. The piece belongs to the Irish Guards who loan it to Kate for the occasion.
And finally, a closer look at Kate's elegant up-do.
