"Raining" style queen: Kate brightens up drizzly premiere

The rainy weather was instantly forgotten as the Duke and Duchess of Cambridge stepped from their car onto the red carpet at a London premiere in aid of William”s Tusk Trust charity.

A sea of flashbulbs greeted William and Kate, elegant in a grey Matthew Williamson dress with subtle peplum detail and jade green beading trim.

Like a true gentleman, the Prince shielded his wife from the rain with an umbrella as they walked to the BFI Southbank.

The couple, who celebrate their first wedding anniversary on Sunday, were out to highlight the opening of the film Big Cats.

The film tells the story of life on Kenya”s plains for a pride of lions and a family of cheetahs as they fight to survive.

It is directed by Guy Ritchie, who was enjoying a night out at the unveiling with his girlfriend Jacqui Ainsley.

Sir Patrick Stewart narrates the true-life story, from which the proceeds will raise funds for the wildlife conservation charity of which William is patron.

The Tusk Trust supports wildlife conservation and poverty reduction from Botswana to Algeria.
