I like to picture Benedict Cumberbatch wearing this with a battered chocolate brown cord jacket. Or maybe with sage velvet. That’s why I’ve stationed myself outside his London townhouse for three weeks. He hasn’t come out. I know he’s in there. When I use my heat sensitive camera I can see him moving about. I’m not confident about getting to hand this over to him before next years Baftas, so I’m putting it on the open market.
