During her first St. Patrick's Day as Colonel of the Irish Guards, Kate Middleton stunned in a turquoise coat and hat.
Middleton acquired a gold Irish Guards Shamrock Brooch for the event.
Middleton handed out shamrocks to attendees and added a large spring of the lucky greenery to her own outfit.
In 2015, she wore a brown cloak and pillbox hat when pregnant with Princess Charlotte.
At a socially distant celebration, Middleton wore a Zara blazer and a vintage coat dress in green.
After the parade, Middleton and Prince William joined troops inside for some friendly chats and a pint of Guinness for a royal toast to the holiday.
