Fashion: Escalators are on the up Last season, models emerged from a steam train with porters holding their luggage; the spring-summer season before that they rode a fairytale merry-go-round. Yesterday, Marc Jacobs chose a rather more prosaic mode of transport for his chosen girls. They made their way on to the catwalk via sets of escalators for his latest collection for Louis Vuitton. Would that the moving walkways in the average mall showed off such fabulous fashion. Jacobs made sure that no heels-catching-in-the-grates incidents occurred by dressing his models' feet in shoes with a heel which looked wide from the back, but stiletto width from the side: fashion forward and practical too.
