Today the Duke and Duchess of Cambridge joined other world leaders in wishing Ireland a Happy St. Patrick's Day in a video message. In a nod to the holiday, Kate wore a green blazer by Zara with Daniella Draper baby shamrock charm hoop earrings and matching necklace, according to Kate's Closet. The Irish Foreign Ministry, which posted the video on their YouTube channel, introduced it with the caption, "We have a saying in Irish: 'Ar scáth a chéile a mhaireann na daoine'. We live in each other's shadows. It speaks to the interdependence of our world. Thank you to friends around the Globe for this #StPatricksDay message."
