Arriving at the Cenotaph on Whitehall for the somber service, the Duchess of Cambridge looked elegant in a double-breasted black coat adorned with a trio of poppies and her hair styled into a side bun under a large black hat.
While she watched on from a balcony with Camilla, Duchess of Cornwall, and Sophie, Countess of Wessex, Prince William stood alongside Prince Harry for the service. The brothers have both served in the armed forces.
The royal family was also out on Saturday for the Festival of Remembrance at London's Royal Albert Hall.
The Duke of Cambridge opted for a navy suit for the evening event, while Kate let her brunette locks down and sported a black Callas evening coat from Temperley London’s pre-fall 2014 collection, accessorizing with a velvet clutch.
