Paris Fashion Week is a clothing trade show held semi-annually in Paris, France with Spring / Summer and Autumn / Winter events held each year. Dates are determined by the French Fashion Federation. Currently, Fashion Week is held in the Carrousel du Louvre, as well as at various other venues throughout the city. Paris Fashion Week is part of the Big 4 fashion weeks internationally, the others being London Fashion Week, Milan Fashion Week and New York Fashion Week. The schedule begins with New York, followed by London, and then Milan, and ending the events in Paris. In 2013, Paris Fashion Week (Fall / Winter season) starts February 26 with Moon Young Hee, and will be followed by shows from major fashion houses such as Louis Vuitton, Comme des Garçons, Christian Dior, Balenciaga, and more. These runway shows are held to show the fashion industry what the various labels will be releasing and to increase sales for the brands. The best models are featured in the shows, and catwalks must be perfected for them.
