The famous British actress Audrey Hepburn made her big break in America with the 1953 film "Roman Holiday," a performance she went on to earn a Oscar for (per IMDb). While her most known film "Breakfast at Tiffany's" wouldn't release until 1961, she was still a well-known actress of the '50s, making her a great Halloween costume pick.
