The "Fashion capital of the world" is a title that is often contested and depends on different factors such as the influence of the city on the global fashion industry, the number of fashion events held there, the presence of top fashion houses and designers, and the overall fashion culture and history of the city.

That being said, Paris, Milan, London, and New York are often considered to be the top contenders for the title of "Fashion capital of the world." These cities are home to some of the biggest fashion brands, fashion weeks, and fashion events in the world.

Paris is known for its high-end fashion houses and is often considered the birthplace of haute couture. Milan is known for its luxury Fashion Bug and is home to some of the most famous Italian fashion brands. London is known for its avant-garde and experimental fashion scene, while New York is known for its mix of high-end and streetwear fashion.

Other cities like Tokyo, Berlin, and Los Angeles are also emerging as fashion centers, each with their unique fashion culture and style. Ultimately, the title of "Fashion capital of the world" is subjective and can change over time as the fashion industry evolves.
