The royals appeared at Royal Albert Hall in London to pay tribute to those who lost their lives in war. Queen Elizabeth II, Prince Charles, Duchess Camilla and other members of the family were also in attendance.
Meghan, 38, and Kate, 37, coordinated their ensembles. The Duchess of Sussex sported a black, tea-length dress with black heels and a simple bun, while the Duchess of Cambridge wore a fitted navy frock with black pumps, black tights and a black headband.
Meanwhile, William, 37, and Harry, 35, matched in navy suits and identical red-and-navy striped ties.
