Kate Middleton and Prince William celebrated St. Patrick’s Day Sunday at the Irish Guards parade at Cavalry Barracks in Hounslow, England. 

The Duchess of Cambridge handed shamrocks to service members at the 1st Battalion Irish Guards St. Patrick’s Day Parade while wearing a gorgeous, emerald Alexander McQueen coat, as identified by People, complete with a matching fascinator. 

She added a rare Cartier shamrock brooch (on loan), and gorgeous green tourmaline and amethyst earrings by Kiki McDonough, according to Harper’s Bazaar.
