Gavin doesn't just dress nice and presentable, he "started" the hipster thing. If you watch his interview videos with people like Joe Rogan, you can see he does a lot more than just "look nice."

He's trying to appeal to the working class and college students by wearing a combination of beer shirts/hats and dress shoes.

Don't get me wrong, I like fashion. However, I'm gay as hell so I know when someone puts the time in (I only rarely do).
