“So what’s Keira Knightley like to work with? She is absolutely delightful, very down-to-earth and totally un-starry. And she was always very interested in her costumes, as all good actresses are. She would often discuss the moods and emotions that were building up in her character and relate the dresses to various scenes. Every dress had a lot of meaning to her performance.” So what did Keira keep? No gowns, thank you very much. The ever-practical actress only hung on to a pair of boots.
