On April 20, Charles and Queen Camilla will open the exhibition "Queen Elizabeth II: Her Life in Style" at the King’s Gallery, featuring about 300 items from the late queen’s wardrobe on view until Oct. 18. The couple will then travel to the U.S. for events marking the 250th anniversary of American independence.
The centennial comes after a challenging start to Charles’s reign, amid his cancer treatment, a strained relationship with his son Prince Harry, and public attention over Prince Andrew’s ties to Jeffrey Epstein. PEOPLE has reached out for comment.
