Actress Amber Heard — you know her from The Informers, Pineapple Express and Zombieland — is quite the transformer. Yesterday, the 24-year-old actress attended a Habitat for Humanity event in Lynwood, California wearing a loose white blouse, jeans, and boots for a super casual look. But later that night she morphed into a glam girl for an InStyle party in Los Angeles wearing a black top and voluminous cream skirt. What a change! Between the ombre hair and the below-the-knee hemline, this is one of our favorite looks of the week. Sometimes simplicity is key.
