Princess Catherine and her daughter, Princess Charlotte, attended the coronation of King Charles III wearing matching silver headpieces. The dress code was intended to be more pared back, with a nod to the king's commitment to protecting the environment. Kate wore drop-pearl earrings belonging to Princess Diana.

They both wore ivory silk dresses embroidered with symbols representing the four nations of the UK, created by Alexander McQueen. The designer also custom created Kate's wedding dress in 2011.
