Cool thing about college! It's not highschool! So you can express yourself without people giving you crap. So, dress how you want to dress or dress according to who you want to appeal to.1

Whatever you want.
That's the thing.
Most people don't bother that much with dressing up, but they don't completely phone it in either.
Casual - cute is the thing most people go for. And when it's exam time - it's way more casual than cute.
There was this one girl who always came to college in extremely high heels, all made up, in skirts and fancy tops. I thought she was always going out rather than going to classes.
Don't go too fancy and don't go too casual - no sweatpants. O. o1
