London Fashion Week is the Big Four’s laboratory — the week most associated with experimentation, emerging designers, and creative risk. It runs second each season, after New York and before Milan, and is organised by the British Fashion Council.
When it runs
London shows immediately after New York each season — February for autumn/winter, September for spring/summer — handing over to Milan next.
What defines it
London is the most experimental stop on the calendar, long associated with directional, avant-garde design and a pipeline of graduate talent (its art-school scene, led by Central Saint Martins, is a global talent source). It is organised by the British Fashion Council, which actively champions emerging designers.
