2016 was undoubtedly a year of flux, instability and uncertainty, with a widespread feeling of fragility that was reflected in the fashion industry as well as the world at large. As in the previous year, in 2016 we saw a significant number of major departures from fashion houses: Hedi Slimane exited Saint Laurent, Peter Copping left Oscar de la Renta after just a two-year stint, Maria Grazia Chiuri moved from Valentino to Dior, Peter Dundas left Roberto Cavalli and the Public School boys stepped down from their roles at DKNY.This year we saw leading brands begin to operate in an entirely new way, shaking up the traditional schedule, whether it was merging menswear and womenswear collections on the catwalk or showcasing in-season collections (rather than presenting designs six months before they hit the shops) with the advent of the “see now, buy now” movement.

Ahead are just some of the biggest fashion moments from the past 12 months...
