Kate Middleton paid tribute to British veterans and troops at the annual Remembrance Sunday Service at the Cenotaph on Whitehall in London. The 33-year-old Duchess of Cambridge sported a chic look, wearing a black double-breasted patchwork felt and velvet coat by her favorite designer, the late Alexander McQueen. She paired it with a black felt hat with a butterfly and a small mesh birdcage veil.
