She's known for her bold red-carpet style, but in the emotionally charged drama I Am Love, which hits select theaters today, Tilda Swinton adopts a more classic look for her role. Set in Milan, the film generated buzz in the fashion world when Jil Sander's Raf Simons took on the project. Says the Belgain designer: "The clothing perfectly defines Tilda's character [Emma], a woman who longs to break out of her world of superficial perfection." The British actress gave us her take on the collaboration: "Through the use of color, Emma stands apart as a potentially rogue element, a molten spirit, but still makes sense within the milieu. Simons's sense of color is supersonic, bright as a daisy. The cut of his clothes makes him an absolute sculptor." The tomato red sheath (left) made such an impression that it is being specially produced for jilsander.com. Click on the gallery to see more of Simons's designs from the film.
