A fashion week is a week-long fashion industry event where fashion designers, brands, or "houses" display their latest collections in runway fashion shows to buyers and the media which influences upcoming fashion trends for the current and approaching seasons. The most prominent fashion weeks are held in the traditional fashion capitals of the world—in chronological order, New York City, London, Milan, and Paris, or the "Big Four" circuit. At times, the Big Four is expanded to the "Big Five" including Tokyo.
