The Duchess opted for a sleek ebony coat dress and midnight-black pillbox hat adorned with an elegant netted veil, finishing off her look with a pair of delicate pearl earrings for the somber occasion which celebrated the life of Britain's longest-reigning monarch.
Her outfit was inspired by past moments celebrating the late monarch's life, with the dress the same style as one worn in 2018 when she celebrated Her Majesty's 92nd birthday at the Royal Albert Hall, and her hat, by Stephen Jones for Dior, the same style she wore in June for the Queen's Jubilee celebrations.
