Fashion is the style and custom prevalent at a given time. In its most common usage however, "fashion" describes the popular clothing style. Many fashions are popular in many cultures at any given time. Important is the idea that the course of design and fashion will change more rapidly than the culture as a whole. Fashion designers create and produce clothing articles.
The terms "fashionable" and "unfashionable" were employed to describe whether someone or something fits in with the current or even not so current, popular mode of expression. There exist a number of cities recognized as global fashion centers or fashion capitals. Fashion weeks are held in these cities where designers exhibit their new clothing collections to audiences. The main five cities are Tokyo, London, Paris, Milan and New York, all headquarters to the greatest fashion companies and renowned for their major influence on global fashion.
