Fashion show finales follow a familiar rhythm: after the models march along the catwalk for a last hurrah, the designer comes out to take a bow. Their demeanour is often telling, an indicator of their attitude to the collection they’ve shown — are they a bag of nerves, or grinning from ear to ear?

Also noteworthy is the look they choose to take their bow in. Are they even wearing their own work? One of the most celebrated designers of our time never wears his own designs. Karl Lagerfeld may create the occasional menswear look at Chanel and he designs a whole men’s collection for his eponymous label but he has long been a customer elsewhere: Dior Homme.

Lagerfeld started wearing Dior Homme when he was in his late sixties, shedding six-and-a-half stone to fit into the skinny styles of the label’s then designer Hedi Slimane. Lagerfeld has stayed loyal to the brand ever since, even after Slimane, now creative director of Saint Laurent, quit in 2006. And although the label is known for its emphasis on youth, Lagerfeld, now in his eighties, remains one of Dior Homme’s most visible clients.
