1. She's been the face of Chanel, now she is portraying Chanel. Keira Knightley has stepped into the legendary shoes of Coco Chanel for a new short film created by Karl Lagerfeld.

French actress Clotilde Hesme, plays her aunt Adrienne, while Stella Tennant, Lady Amanda Harlech and her daughter, Tallulah, also star in the film.

Prada Gatsby costume2. Miuccia Prada has been talking Gatsby, and I am listening. She has collaborated with film costume designer, Catherine Martin, on the stunning 1920s wardrobe of Buz Luhrmann's film remake. Prada contributed 40 looks for the movie's two party scenes, one of which includes Daisy's "chandelier dress" taken from Prada's spring 2010 collection.

"It was meant to be about light. it became about money, because [Luhrmann] wanted to show her as the most beautiful and rich woman on earth." I ask you - has there been a bigger build-up to a film before? {WWD}
