College was fun because you first discovered MF Doom and Broken Social Scene, and dressed accordingly. Skinny jeans, graphic tees, and hoodies were your go-to kit, and there was absolutely zero reason for you to change that. Now, you've been thrust headfirst into the real world, and you no longer like the angsty indie rock or underground hip-hop you're into.
Sometimes you can just tell the types of people who never really left a certain era because of their style. You don't want to be one of those people. The older you get, the less your outfit should say about the shit you're into. It's time to invest in some quality basics and grow up a little.
