This would be a typical school day outfit. This is casual and laid back but still looks good, which is what you want to go for when attending school. I would wear a watch with this outfit to go along with it.
This is definitely a hipster outfit for guys. It includes a long sweater, a shirt that matches the sweater (of course), a belt, a nice pair of jeans, and what appears to be a fashionable version of combat boots which are in style right now.
