This practical explanation differs from a popular theory among fans of Princess Diana, who believe the Queen wore white as a subtle tribute to Charles’s first wife, who passed away in 1997. Some supporters have interpreted the choice as a quiet sign of respect.

Charles and Camilla’s relationship had long drawn public attention, especially since it overlapped with his marriage to Diana. Diana herself once famously remarked in a BBC interview that “there were three of us in this marriage,” highlighting the controversy.

Despite earlier reservations, particularly due to her role as head of the Church of England and the fact that Camilla’s former husband was still alive at the time, Queen Elizabeth II ultimately gave her approval for the marriage. However, she did not attend the later religious blessing at St George’s Chapel.
