This week we saw some looks we won't be forgetting for a while. Jennifer Aniston wore an unexpected floral Dior frock at the London premiere of We're the Millers, Lily Collins channelled Rooney Mara's style in a striking Cushnie Et Ochs dress and Kerry Washington wore the coolest Stella McCartney dress ever.
Check back daily to see Stylist's guide to what all the stars wore at premieres, parties and events this week.
