I love the fact that Sienna Miller and Keira Knightley hit it off so well on the set of their newest film The Edge of Love and have brought us some great moments on the red carpet and in interviews since wrapping. But I'm also loving the '40s fashion they're sporting on screen - from the granny cardies to the floral tea dresses and even the folded down wellies. See the girls (and Keira's mum) dish on the wardrobe, the characters and the story.
