Kate Middleton and Prince Harry attended the Irish Guards' St. Patrick's Day Parade in Aldershot, United Kingdom, on Monday.

The Duchess of Cambridge wore an emerald green trenchcoat with sprig of clovers attached to her chest. She wore a matching hat and pumps with diamond earrings.

They visited the First Battalion Irish Guards at Mons Barracks. Middleton presented the traditional shamrock sprigs to the Guards.

The couple recently returned from a vacation in the Maldives.
