The royal couple, who are set to celebrate their first wedding anniversary, stepped out Wednesday for the London premiere of the Disney Nature film, African Cats.
The Duchess of Cambridge wore a tailored gray Matthew Williamson peplum dress with a jeweled turquoise hem to the event, which benefitted one of her husband's charitable causes, the Tusk Trust charity.
The film tells the story of a pride of lions and a family of cheetahs.
It's the first event for William and Kate since he returned from military service in the Falkland Islands.
