Every year, New York Fashion Week is the first of the four.

Fashion Monday, which began in 1943, was organized by the New York Dress Institute (NYDI).

The New York Fashion Institute was founded in 1940 to promote the sales of clothing manufactured in New York.

In the post-war depression, the mayor of New York City, Fiorello La Guardia, found that the city could only rely on employers in the fashion industry, and that economic factors and loyalty were the main considerations at the time, not designers.

Before the establishment of the Council of Fashion Designers of America, the dominant American fashion industry also included the New York Couture Group.

Arnold Scaast, the association's designer, later recalled that many of the group had gone to Paris to copy boards. "We were not like the garment manufacturers," he said. "Creativity was a big word at the time."

In "IMPACT," a history of the Council of Fashion Designers of America, you'll read that it wasn't until the '90s that the council realized that real impact required events, which were more effective than awards.

The "New York Fashion Week" organized by the association began to take shape in the 1990s.

Initially, fashion Week was conceived as a way to support both worthy designers and members of parliament (almost understood as a performance project), but over the years, sales have been exceptionally successful and the scale has grown.

The biggest change was made by Stan Herman, who served as chairman from 1991 to 2006.

During his tenure, he assembled his scattered shows in New York and brought them to a relatively permanent location, Bryant Park. Herman has also made the Council of Fashion Designers more democratic, for example, by changing its old membership invitation to an open membership application.

Lin Jian, a fashion columnist, believes that the success of a fashion week is judged by "whether there are designers coming out of it."

By that standard, the brands coming out of New York Fashion Week include Calvin Klein, Ralph Lauren, Marc Jacobs, Diane von Furstenberg, Donna Karan and Michael Kors.

But of the four major fashion weeks, New York Fashion Week is best known for its commercialization, which is run by a number of companies, including IMG.

At the same time, New York Fashion Week encourages designers to focus more on the domestic market. Now there is a sense that Shanghai may become more like New York when it comes to commercialisation.
