If you don't already know Imogen Poots, be prepared to become very well acquainted with her. The young actress is about to appear in She's Funny That Way with Jennifer Aniston  and Owen Wilson , after appearing in a series of big hits in 2014. But fashion fans may know her better as the face of Marni for H&M and Chloé fragrance. Since her breakout role in the horror film 28 Weeks Later, she's been a firm favourite with fashion brands for her quirky English rose look, wavy blonde hair, and model figure (her older brother is actually a male model). Imogen favours brands with a sense of fun like Prada, Miu Miu, and Marni, but she isn't afraid to pull out all the stops in a dramatic gown by Givenchy or Nina Ricci. Take a look at some of her fashion moments to date, and watch this space for more from one of our new red carpet favourites.
