In the age of the hoodie-clad Silicon Valley billionaire, it is not the man in the suit but the man who dares to wear a crumpled T-shirt next to him who is making the power move with his wardrobe.

Tom Hardy illustrated this point beautifully on Sunday night with creased jeans, grey trainers and a top from Rug Man Art. The T-shirt was illustrated with the face of a man who looked spookily like Hardy himself, genetically spliced with Billy Gibbons. The Mark Zuckerberg prize for dressing-down, however, was clinched with a sweat band worn high on his left arm; its locker-room connotations bravely at odds with the red carpet.

Leonardo DiCaprio’s very MOR suit and shirt – top button undone like Nick Clegg during an “at home with” – didn’t stand a chance.
