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.

Ready-to-wear (RTW) – also called prêt-à-porter, or off-the-rack or off-the-peg in casual use – is the term for garments sold in finished condition in standardized sizes, as distinct from made-to-measure or bespoke clothing tailored to a particular person's frame. In other words, it is a piece of clothing that was mass produced in different sizes and sold that way instead of it being designed and sewn for one person. The term off-the-peg is sometimes used for items other than clothing, such as handbags. It is the opposite of haute couture.
