My take (as a straight male who cares about style and what not)
Is that he's a good looking guy, but he's one of the guys whose look is defined by how he grooms himself. If not for the way he grooms and styles himself, he definitely wouldn't stand out from the crowd (wouldn't make you turn away either of course)
But after all, he definitely has one of the coolest personalities in show biz, and it makes his look what it is...
A lot of people ask me if I base my style off of him, and I'm like, whaaaaaat. I hadn't even heard of him untill he was on a Have I Got News For You repeat. Which annoys me. But that's not his fault. But uh, yeah, he is, enough. Not really my type, 'cos he's hairy, hahaha.
