Duchess Kate is elegant in Catherine Walker for St. Patrick's Day parade

The Duke and Duchess of Cambridge kept up with tradition today, attending the St. Patrick's Day parade in Aldershot, England. As they've done for the last few years, Their Royal Highnesses visit the scouts at Mons Barracks, William attending as Colonel of the Regiment and the Duchess to present the traditional sprigs of shamrocks to the officers and guardsmen (and one very cute canine mascot!).

Duchess Kate looked lovely in head-to-toe brown, wearing a coat by Catherine Walker, Lock & Co hat and brown suede Emmy heels (these look like the Valerie style, in Chocolate). In past years, our favorite royal has worn all green to celebrate St. Patrick's Day, but kept her look festive this year with a bright sprig of shamrocks and a gold Cartier shamrock brooch that formerly belonged to the Queen Mother.

The Duke and Duchess are readily preparing for Royal Baby number two, expecting the newest Prince or Princess at some point this April. We're sure it will come down to how Kate is feeling, but we don't expect to see her too much over the next couple weeks! Kate has one more engagement on the books tomorrow, where she'll visit a Children's Center in London.
