Fashionistas teetered along to the Serpentine Gallery last night to join the grand dame of British fashion, Vivienne Westwood, for the launch of her new monolithic tome, The Vivienne Westwood Opus. In a fitting tribute, plenty of her corseted, punky creations were modelled by guests including designer Jasmine Guinness, artist Tracey Emin and buxom burlesque saucepot Immodesty Blaize.
