After having shown her clothes on the runways of Milan and Paris since 1982, Dame Vivienne Westwood made a dramatic return to the city that made her a fashion star for London Fashion Week Men’s.

“The last thing I’m interested in is keeping up with the times,” Ms. Westwood said as a swarm of photographers stood nearby. “I prefer to go faster than that. I have to. We are living in an age where we face disaster at almost every turn.”
