The event, organized to commemorate Britain's dying war, is held annually at the Royal Albert Hall. The Bateau collars have been associated with Meghan Markle, leading to speculation that dress selection may have been designed as a tribute.
The remembrance is the first public appearance of the two Duchesses since Prince Harry confessed to an ITV documentary in which he and Prince William grew slightly apart.
Kate wore a dark navy blue dress wrapped around her waist with a smart black belt.
The dress was a collar collar, a design option often chosen by Meghan.
The outfit was accompanied by a black headband and Jimmy Choo black velvet pumps.
Three red poppy dresses, which were the news of those who died in the British armed forces, were attached.
Prince William also wore a poppy attached to his dark suit adorned with two medals.
Meghan was wearing a black dress with floral ornaments.
He had a wide black belt around his waist and was tied with three buttons on the front.
