The Duchess wore the floor dress for the first time during a British Olympic event in 2012.
Prince William, who was the royal patron of Tusk since 2005 , wore a tuxedo and a poppy on the cuff in honor of the Day of Remembrance and the imminent centenary of the Armistice.
Tusk works to protect African wildlife and fights the illegal trade in animals including elephants, and Prince William at the start of this year visited Tusk projects in Namibia and Tanzania.
The award ceremony was to recognize people who were working at the forefront of the fight against poaching.
Tusk's nominees, supporters and sponsors attended the event, where Prince William delivered a speech and distributed three prizes.
