Today, The Duke & Duchess visited the 1st Battalion Irish Guards at the St. Patrick’s Day Parade at Cavalry Barracks, Hounslow.

St. Patrick’s Day is a traditional regimental celebration for the Irish Guards who are part of the Foot Guards Regiment involved in state ceremonial duties. The Queen is the Irish Guard’s Colonel-in-Chief, and The Duke was made Colonel of the Regiment back in 2011. During the parade, The Duchess presents springs of shamrock to the Officers and Guardsmen of the Regiment — a tradition started by Queen Alexandra in 1901. It was Queen Victoria who first instructed all ranks of her Irish regiments to wear a sprig of shamrock in their headdress to commemorate the gallantry of her Irish soldiers. The Irish Wolfhound Domhnall is their mascot, and he also receives a sprig of shamrock.

The Duchess was dressed in festive St Patrick’s Day colours.  We saw the return of Kate’s bespoke green Catherine Walker coat worn in Stockholm, Sweden in January. Once again, she paired it with her Troy London faux-fur collar (£65) and cuffs (£40). Kate also brought back her beautiful Gina Foster ‘Meribel Felt Hat With Bow’ (originally £535). This hat is made to sit on the right side of the head and is secured by an elastic that sits under the hair. Kate wore this to the 2014 parade too, as well as to the Christmas church service in 2013.

Her gloves are the Cornelia James ‘Imogen’ merino wool gloves that are available for £70 in multiple colours.
For jewellery, The Duchess had on her Kiki McDonough ‘Special Edition Green Tourmaline, Green Amethyst and Diamond Earrings’ which were made to celebrate the birth of Charlotte. She also wore her trusty Tod’s block heel pumps and black tights. The look wouldn’t be complete without the Cartier gold three-leaf shamrock brooch, pinned just above her sprig of shamrock. This actually belongs to the Irish Guards, who have loaned it to The Queen Mother, The Princess Royal and now The Duchess of Cambridge.

On St Patrick’s Day 2013, Kate stepped out in a green Emilia Wickstead fit-and-flare dress coat.

Two years later, Kate covered her baby bump with a brown Catherine Walker coat.
