Runways can't compete with Britex' fashion drama since 1952. First floor: designers bicker over dibs on caution-orange chiffon. Second floor: glam rockers dig through velvet goldmines. Third floor: Hollywood costumers make vampire-movie magic with jet buttons and hand-dyed ribbon. Top floor: fake fur flies and remnants roll as costumers prepare for Burning Man, Halloween and your average SF weekend.
