There are two major seasons per year - Autumn/Winter and Spring/Summer. For Womenswear, the Autumn/Winter shows always start in New York in February and end in Paris in March. Spring/Summer shows start in September in London and end in Paris in October. Menswear Autumn/Winter shows start in January in Milan for typically less than a week followed by another short week in Paris. Menswear Spring/Summer shows are done in June. Womenswear Haute Couture shows typically happen in Paris a week after the Menswear Paris shows.
Over the past few years, more and more designers have shown inter-seasonal collections between the traditional Autumn/Winter and Spring/Summer seasons. These collections are usually more commercial than the main season collections and help shorten the customer's wait for new season clothes. The inter-seasonal collections are Resort/Cruise (before Spring/Summer) and Pre-Fall (before Autumn/Winter). There is no fixed schedule for these shows in any of the major fashion capitals but they typically happen three months after the main season shows. Some designers show their inter-seasonal collections outside their home city. For example, Karl Lagerfeld has shown his Resort and Pre-Fall collections for Chanel in cities such as Moscow, Los Angeles and Monte Carlo instead of Paris. Many designers also put on presentations as opposed to traditional shows during Resort and Pre-Fall either to cut down costs or because they feel the clothes can be better understood in this medium.
Some fashion weeks can be genre-specific, such as a Miami Fashion Week (swimwear), Rio Summer (swimwear), Prêt-a-Porter (ready-to-wear) Fashion Week, Couture (one-of-a-kind designer original) Fashion Week and Bridal Fashion Week, while Portland (Oregon, USA) Fashion Week shows some eco-friendly designers.
