New York Fashion Week (NYFW), held in February and September of each year, is a semi-annual series of events in Manhattan typically spanning seven to nine days when international fashion collections are shown to buyers, the press, and the general public. It is one of four major fashion weeks in the world, collectively known as the "Big Four", along with those in Paris, London, and Milan. The Council of Fashion Designers of America (CFDA) created the modern notion of a centralized "New York Fashion Week" in 1993, although cities like London were already using their city's name in conjunction with the words fashion week in the 1980s. NYFW is based on a much older series of events called "Press Week", founded in 1943. On a global scale, most business and sales-oriented shows and some couture shows take place in New York City.

Paris Fashion Week is a series of designer presentations held semi-annually in Paris, France, with spring/summer and autumn/winter events held each year. Dates are determined by the Fédération de la Haute Couture et de la Mode. Paris Fashion Week is held at venues throughout the city.
