ok, I know, I know, bags seem weird to carry around and not many guys do. But I mean, they're convenient, are they not? You can keep all your shit in one place without having to stuff it all in your pockets. It works for laptops and its way easier to get away with if you're a student. Or wearing a suit. Because guys in suits can get away with a lot. As long as you're not toting around the latest Chanel clutch or anything, you should be fine.
