Kate Middleton made her first red carpet appearance since the birth of son Prince George.

The Duchess of Cambridge accompanied her husband, Prince William, to the Tusk foundation gala dinner at The Royal Society in London.

Middleton, who gave birth to their first child July 22, looked stunning in a glittery floor-length, silver-sequined Jenny Packham dress that she paired with sparkly stilettos.

William is a patron of the Tusk Trust, a British charity that funds conservation projects in Africa - a cause close to his heart.

After announcing today that he had completed his final duties as a search-and-rescue helicopter pilot with the RAF and ended his military service of seven years, the Duke of Cambridge is now looking to expand his charity work, particularly in the field of conservation and endangered species.

Prince William Announces Career Change

Kate, 31, made her first public appearance since Prince George's birth at the end of last month, when she came as William's surprise guest at the kickoff of the 135-mile Ring O' Fire marathon in Anglesey, North Wales.

The duchess donned skinny jeans, looking as glamorous as ever, showing she's shed that baby weight.
