I chose Fabio to be on my first page in GQ two years ago because of total unconscious style like this. "Unconscious Style" that sounds like a good phrase.
Anyway, Fabio is just full of these little quirks and it is so charming. He almost tries to hide them (if you can hide walking with your hand in your coat?) because he is actually very shy. If you notice I haven't shot him standing still in quite a while because he hates posing for pictures so much.
