Party people, take note: your name's not down at LFW unless you're wearing something shiny. Just check out Cara Delevingne and BFF Clara Paget, both wearing shimmering metallics to the W magazine party at The London Edition hotel; Eliza Doolittle in ice-blue trousers at the Julien Macdonald show; and Alexa Chung, who wore a black patent dress (teamed with a bobbly cream jumper and gingham Mary Janes) to Longchamp's flagship shop launch party. You've seen how they do it, now it's your turn to shine.
