London Fashion Week partying kicked off in serious style at Number 10 last night and our very own editor-in-chief Jane Bruton and style director Paula Reed were among the fashion big-hitters invited. Sarah Brown hosted a champagne reception to celebrate 25 years of British Fashion. She rallied members of the fashion community - from the British Fashion Council's Hilary Riva and Harold Tillman, to designers Luella Bartley, Todd Lynn and Anya Hindmarch, plus supermodels Naomi Campbell and Erin O'Connor - in support of London Fashion Week, amidst threats from the US that it should be cut down to just four days. The British Fashion Council used the event to announce a new annual award for young designers, funded in the first instance by Erin O'Connor auctioning off key pieces of her wardrobe (see this week's Grazia for the low-down). But what really went on behind the politics? Sarah Brown, wearing a Jaeger shift, seemed relaxed and at home, laughing with us about missing her deadline for the piece she's halfway through writing for Grazia. As for the rest of the guests? It was a bit like designers letting off steam after a hardcore day of shows. Julien Macdonald sneaked his parents in on their bus passes, Gareth Pugh got told off for taking a picture in the cabinet rooms, and Henry Holland munched mini apple pies and took great delight in checking out the environmentally friendly lights - which made everyone look, frankly, hideous. Sure there were swirly carpets on the floor but we were amazed by the paintings at No 10 - a room full of Turners and Constable's first-ever portrait. An iconic LFW night... Check out the pictures below to see who was there and what they wore.
