For their second royal outing of the day, William and Kate made their grand arrival at a reception to launch the Imperial War Museum Foundation's 'First World War Galleries: Centenary Campaign.'
The Duke and Duchess of Cambridge were helping to launch a campaign to create new First World War galleries in time for the centenary of the conflict in 2014.
Kate wore an £450 Amanda Wakeley panelled charcoal grey dress with three-quarter length sleeves. This dress is the charcoal version of that oatmeal-toned frock she wore at the opening of the Oak Centre for Children & Young People.
She added a little pizazz with a striking Alexander McQueen gold and black chain belt (2,225) and black Jimmy Choo 'Cosmic' heels. She also carried a black Anya Hindmarch Maud clutch. Topping off her accessories, she wore her Temple of Heaven 9ct yellow gold Girandole earrings by Cassandra Goad (£1,220).
Kate pulled out the stops with her super sophisticated hairstyle. She decided on a half up-do, with some curls twirled into a loose bun, and the rest cascading down her shoulders.
