The Duchess was in a familiar look for today’s Order of the Garter events.
The Order of the Garter is the UK’s oldest and highest order of chivalry. Prince William was appointed in 2008, below we see him with Prince Charles as they walk into St. George’s Chapel today.
The honor is determined solely by the Queen, input from Ministers and others is not required. It is HM who decided in 1987 that women should also be included in the Knighthood, Lady Margaret Thatcher is one of those so honored.
