New York Fashion Week
Held in February and September of each year, is a semi-annual series of events (generally lasting 7–9 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 4”, 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.
It has consisted of numerous branded events, such as Olympus Fashion Week New York and MADE Fashion Week, and many independent fashion productions around town.
Producers of New York Fashion Week include IMG, The SOCIETY, in conjunction with Fashion Week Online, and Art Hearts Fashion. A centralized calendar of citywide events (including those affiliated with WME/IMG) is kept by the CFDA, and was acquired from calendar founder Ruth Finley. The economic impact of New York Fashion Week is estimated at $887 million.
London Fashion Week
Organised by the British Fashion Council (BFC) for the London Development Agency with help from the Department for Business, Innovation and Skills, London Fashion Week first took place in October 1983. It currently ranks alongside New York, Paris and Milan as one of the ‘Big Four’ fashion weeks. It presents itself to funders as a trade event that also attracts significant press attention and benefit to taxpayers. It states that it is attended by over 5,000 press and buyers, and has estimated orders of over £100 million.A retail-focused event, London Fashion Week Festival, takes place immediately afterwards at the same venue and is open to the general public.
During SS16 (shown September 2015) and AW16 (shown February 2016), British Fashion Council made the decision to host the designers’ showrooms to the ‘Vinyl Factory’, situated at the active car park in Soho, off Brewer Street. 
Following increasing numbers of anti-fur protesters, the London Fashion Week held in September 2018 is set to be the first major fashion week to be fur-free.
Milan Fashion Week
Milan Fashion Week, established in 1958, is part of the global “Big Four fashion weeks“, the others being Paris Fashion Week, London Fashion Week and New York Fashion Week. The schedule begins with New York, followed by London, and then Milan, and ending with Paris.
Milan Fashion Week is partially organized by Camera Nazionale della Moda Italiana (The National Chamber for Italian Fashion), a non-profit association which disciplines, co-ordinates and promotes the development of Italian fashion and is responsible for hosting the fashion events and shows of Milan. The Camera Sindacale della Moda Italiana, was set up on 11 June 1958. This was the forerunner of the body which subsequently became the Camera Nazionale della Moda Italiana.
Proprietors of the most important establishments in Italy, including some private establishments, which, in those days, played a crucial role in the promotion of this sector, were present at the Memorandum of Association: Roberto Capucci, Emilio Schuberth, Maria Antonelli, Princess Caracciolo Ginnetti, Alberto Fagiani, Giovanni Cesare Guidi, Germana Marucelli, Simonetta Colonna Di Cesarò, Jole Veneziani, Francesco Borrello, Giovanni Battista Giorgini, and the lawyer Pietro Parisio.
The events dedicated to women’s fashion are the most important (Womenswear / Milan SS Women Ready to Wear, and Milano Moda Donna being the major fashion shows). The summer events dedicated to men include Menswear and Milano Moda Uomo.
In 2013 the autumn/winter Milan Fashion Week started on 20 January with Paola Frani, and was followed by shows from major fashion houses such as Armani, Roberto Cavalli, Dolce & Gabbana, Etro, Fendi, Ferragamo, Gucci, Jil Sander, Marni, Max Mara, Missoni, Moschino, Philipp Plein, Prada, Pucci, John Richmond, Tod’s, Versace etc. but also by shows from new labels and younger designers such as Au jour le jour, Cristiano Burani, Gabriele Colangelo, Marco De Vincenzo, Stella Jean, Chicca Lualdi, MSGM, N°21, Fausto Puglisi, Francesco Scognamiglio etc. On 20 November 2013, Giorgio Armani announced he has decided to join the Italian Chamber of Fashion.
In April 2015, Carlo Capasa was named president of the Camera Nazionale Della Moda Italiana.
Certain shows are not held in conjunction with the Camera Nazionale Della Moda Italiana, including Dolce & Gabbana. The Camera Nazionale Della Moda Italiana has also been sharply criticized by designers such as Cavalli.
Paris Fashion Week
Paris Fashion Week (French: Semaine de la mode de Paris) is a series of designer presentations held biannually in Paris, Francewith spring/summer and autumn/winter events held each year. Dates are determined by the French Fashion Federation. Paris Fashion Week is held at venues throughout the city.
In addition to ready-to-wear shows, there are men’s and haute couture shows, which are held semiannually for the spring/summer and autumn/winter seasons. Also, every year, famous brands like Dior, Chanel, Louis Vuitton, Givenchy, and Céline host their shows in historical places such as the Carrousel du Louvre and the Grand Palais
Los Angeles Fashion Week
Fashion Week in Los Angeles occurs biannually. Multiple show producers hold events throughout the Greater Los Angeles area each March and October. Traditionally, the City of Los Angeles identified the third weekend of those respective months as the beginning of its Fashion Week. However, new independent event producers have been transitioning Fashion Week related activities to coincide closer in time with the LA Fashion Market Week.
Los Angeles Fashion Week was created as a West Coast alternative to New York Fashion Week, originally Press Week, which was created by Eleanor Lambert in 1953. Independently produced events, working alongside designers began inviting fashion journalists to see collections from Southern California. Since the late 1990s, Fashion Week has been represented by a community of L.A. fashion producers, designers, journalists, and marketers interested in its success.
Miami Swim Week
Miami Swim Week occurs annually through multiple show producers holding events through the greater Miami area, more specifically Miami Beach every July.
For the uninitiated, Miami Swim Week is for all things beach (and pool, and summer in general). And in the ten years since its inception, it’s gotten seriously huge.
What began as just a handful of shows has now grown to include presentations from 50 brands at a variety of venues both official and not; this year alone attracted more than 600 media outlets and buyers from all over, accounting for a chunk of the 10,000 guests who made their way to Florida. It is, without a doubt, the most important event for swim and resort wear in the country—if not the world.
