Kate Moss is the fresh face of YSL advertising campaign

Twinkling: the model in a star-printed long-sleeved silk dress

But in the photos where we can see Moss clearly, she looks reborn and immaculate.

"This collection was focused around iconographies," Pilati said. "And in fashion, Kate Moss is one of the great icons. I am particularly drawn to her versatility as a model, and of course to her timeless beauty."

Chameleon Kate is nothing if not versatile: this season she personifies the "London look" for high-street make-up brand Rimmel, is grown-up and sophisticated for American designer Donna Karan, and now embodies timeless luxury for YSL. Three seasons ago, Moss appeared in 14 campaigns; the supermodel has been more selective this time.
