The Roaring 20s were dominated by jazz and organized crime. Think Charlie Chaplin, Al Capone and Art Deco for your Twenties fancy dress ideas. The 30s were known as The Golden Age of Hollywood, as full colour film was made possible. Classics include Gone With The Wind, The Wizard of Oz and Disney's Snow White and the Seven Dwarves. In music, jazz morphed into swing and boogie-woogie.
