But in New York this week, where he was shooting model Stella Tennant for an forthcoming Chanel campaign, he didn't even have to say anything to keep us amused. Simply by donning a bottle green tweed jacket in place of his habitual black created a stir.
He once told US Harpers Bazaar about his personal uniform of black, saying, '[It] is actually two looks a special jacket with tails made by Dior, but not what you wear for weddings Then I have another jacket I love from the new Dior men's collection.
He also made sure to clarify, I bought five of [the jacket] so people think I wear the same thing every day, but in fact it's never the same thing.
If you look a little longer at this new picture, youll notice that the new colour is not all. Karls tie-pin is a giant bumblebee rendered in gold. Is he trying to tell us something? Save the bees? Its not easy being green? It would certainly tie in with the eco-friendly renewable energy source showcased at his Chanel spring/summer 2013 show earlier this month, if it was.
