When Vogue and Chanel team up to host a party (or in this case, a film screening of The Duchess), you instantly know you're going to get a lot of bang for your bucks. How about Keira Knightley looking stunning in Chanel Haute Couture for one? Or Keira's Duchess co-star, Dominic Cooper, looking ever-so debonair posing with Anna Wintour's daughter Bee Schaffer. And even a bit of Anna Wintour herself thrown in for good measure too!

Obviously, the star who the shone the brightest was always going to be young Keira, and I was glad to see she stepped it up a notch from the London premiere, with this gorgeous noir gown, Bulgari jewellery and Gina shoes.
