Kenzo’s design duo Carol Lim and Humberto Leon said goodbye to the French label with Solange as the surprise performer in the same Paris stadium which Elton John had packed to the rafters a few nights previously.

The Californians’ ended their eight-year reign with a bang as the American star appeared on a platform to sing “I’m a Witness” in between the men’s and womenswear lines.
