The Duke and Duchess of Cambridge celebrated St. Patrick’s Day on March 17, 2014 by visiting the 1st Battalion Irish Guards in Aldershot, England. The duke is royal colonel of the Irish Guards. The couple presented Shamrock sprigs to the regiment, and the duchess presented sprigs as well to Domhnall , the Regimental Mascot. In keeping with the spirit of the day, Catherine wore green from head to toe: a coat by Hobbs and a hat by Gina Foster. During the course of their visit the couple sampled some sherry and William drank some Guinness. The couple also posed for the obligatory photograph with the regiment. Photos by Getty Images.
