The runway show could consist of the standard parade of looks, ended by all the models doing their strut, finished off with the designer walking out for a final wave. Or sometimes the producers get more inventive by, say, showing a short art film before the show or having a surprise musical guest performance, like last season when St. Vincent sang at the DVF show (and Diane ended up grooving alongside the models) or when Paloma Faith, backed by a live orchestra, crooned at last season’s Burberry show at London Fashion Week.
