The latest? A tiny tweak to Prince William’s uniform that honored both his father and late grandmother, Queen Elizabeth. The update was first spotted during an investiture ceremony held at Windsor Castle on Wednesday in which the Prince of Wales distributed honors to a handful of athletes and former palace advisers while wearing his traditional military uniform. Although nothing seemed out of the ordinary upon first glance, a closer inspection of William’s uniform revealed that two royal cyphers had been placed on the right shoulder strap of his coat.

According to Hello!, the addition of these pins is meant to signify the Prince’s role as an aide-de-camp to the late monarch and the current king. The sentimental gesture comes just days after William declared his loyalty to King Charles in a much more direct manner during Saturday’s coronation service. Shortly after his father’s crowning, Prince William kneeled before the king to pledge his allegiance. "I, William, Prince of Wales, pledge my loyalty to you and faith and truth I will bear unto you, as your liege man of life and limb. So help me God,” William said, appearing to get emotional in the process.
