New exhibition explores the history of catwalk presentations

From early 20th couture salons to modern day fashion shows, an immersive exhibition looking at the history of catwalk presentations opens in London this week. David Sabel, executive producer of Lightroom and "Vogue: Inventing The Runway" said the exhibition, which covers over 150 years of history, shows how the runway show went from "very intimate, private, exclusive salon shows to the kind of multimedia spectacles that they are today."
