Ready-to-wear clothes have elements of haute couture and mass market. They are not made for individual customers, but great care is taken in the choice and cut of the fabric. Clothes are made in small quantities to guarantee exclusivity, so they are rather expensive. Ready-to-wear collections are usually presented by fashion houses each season during a period known as Fashion Week. This takes place on a city-wide basis and occurs twice a year. The main seasons of Fashion Week include, spring/summer, fall/winter, resort, swim, and bridal.
