By Alexandria Sage PARIS (Reuters) – While most other fashion designers may settle for the usual trappings of their business – a dark room, straight runway and phalanx of bored-looking models – Karl Lagerfeld likes to have fun. For Chanel's haute couture collection in Paris on Tuesday, creative director Lagerfeld presented no less than an orchestra, a revolving stage, two curving staircases and over 60 suits and dresses in sorbet shades for Spring/Summer 2014. Under the soaring ceiling of the Grand Palais, the rapt audience was treated to a frothy and oh-so-chic spectacle as models in sparkly sneakers skipped down the stairs to musical accompaniment.
