The first big show of New York Fashion Week will not take place in a traditional space. It is not even on the traditional schedule, which lists roughly 150 shows stretching from Thursday morning to next Thursday night.

Rather, it will take place in the behemoth environs of Madison Square Garden, will feature not only a clothing collection but also an album release, and will be attended by a select group of editors, critics and retailers, as well as a much larger group of ticket-buying consumers, who will fill out the more than 18,000 seats and who are paying up to $8,584 on resale sites for the privilege. (The official price of the tickets was $50 to $135.) For those who cannot make it, the show will be filmed and screened in theaters in 25 countries, including Macedonia and Australia.

The event is the debut of Kanye West’s Yeezy Season 3 as well as the unveiling of his album “The Life of Pablo.” While you could dismiss it as a distraction from the business at hand — a piece of theater from an outsider — something else is to happen three days later that casts the Yeezy experiment in a somewhat different light.

On Sunday, Diane von Furstenberg, the founder of the brand that bears her name and, as the chairwoman of the Council of Fashion Designers of America, a pillar of the fashion establishment, will hold her own “experience” over two floors of her meatpacking district headquarters-New York pied-à-terre (she lives on the top floor).
