"Insights into King Charles III's Coronation and Royal Protocol Changes"

King Charles III's coronation dress code will be a "massive change to royal protocol," according to his former butler Grant Harrold. While historically aristocracy would wear coronation robes, most royals will wear suits instead. Harrold predicts that the female royals will wear dresses during the day and ball gowns for the evening event, but no tiaras. King Charles and Queen Camilla will likely wear ceremonial robes, and guests will wear day dresses and hats. Kate Middleton teased that her coronation outfit will have a "hint of blue."
