London's autumn fashion jamboree wraps up on Tuesday, with the last few catwalk shows and presentations. But this year, as the staff collect up the champagne flutes and stack the chairs, the aftermath is not quite business as usual. There has been much talk of the new "see now, buy now" trend that upends the traditional system whereby fashion houses showcase their new styles but only deliver them to the market several months later. London Fashion Week comes around twice a year (in September and February), and, as the people behind it are keen to emphasise, it is about a great deal more than hats and hem lengths. It is the industry's trade show: new styles are launched, fashion journalists take copious notes, and buyers put in orders for stock.
