The reason Princess Kate — who is known as the Duchess of Rothesay while in Scotland — was not dressed in robes is because Charles, 74, Camilla, 75, and William, 41, are all part of the Order of the Thistle, thehighest order of chivalryin Scotland. The trio all wore Order of the Thistles robes, while Camilla’s robes were paired with afeathered capfeaturing a large white plume.

Per the royal family’s website, King Charles is sovereign of the Order, and “appointments made to the Order are entirely his personal gift, in recognition of men and women who have held public office or have contributed significantly to national life.”

In addition to the 16 knights and ladies of the Thistle, Queen Camilla, Prince William and King Charles’ sister,Princess Anne, were also appointed as Royal Knights of the Thistle. The Order is second only in precedence in England to the Order of the Garter.
