My fashion sense might be kind of conservative, but what the fuck, yo. First off, those shorts are over his kneecaps. You should never, under any circumstances, have your kneecaps out in public unless you about to do a cannonball into the pool.
Two, I hate HATE when motherfuckers wear long-sleeve clothes with shorts. That is a pet peeve of mine. The scarf makes it worse. It's like a seasonal mullet: Winter/Fall on the top, Spring/Summer on the bottom.
