For guys who use them to solve bedhead, these are not fine.

Socks with sandals

Oh, come on.

Wearing the same jeans/shirt/shorts 3+ days in a row

This is not a sartorial issue. It's an olfactory one.

I know you don't care what people think. You are your own man/woman. You are a pioneer. You are an island.

And you will remain one if you stink. Your philosophy professor may wear a five-year beard, smell like a middle school gym and take you to a higher intellectual plane. But your body is still down here, and other students have to sit near it.

Many of today's commercial washing machines take credit, so you have no excuse. Three days in a row? Just say no.

Popped collars

The 26-year-old male model who's wearing a quart of airbrushed makeup and posing by the art building is working. So is the woman photographing him. They work for the Gap.

Now maybe you also work for the Gap, but not as a model. And I guarantee that lime green polo with the collar sticking up isn't working for you.

There is at least one entire website dedicated to the type of guy who wears a popped collar. Don't be that guy.

Staying oblivious

I managed to do this my entire freshman year. My feet weren't just tortured with Tevas and socks. They were tortured with Tevas and argyles. (One girl hung out with me out of pity; the rest kept their distance.)

My guess is that you're also guilty of at least one of the above. And that was fine for high school, assuming it didn't violate your dress code. But you're in college now.

It's true that discovery is all part of the college experience. Women will discover that guys love plaid shorts, sleeveless shirts, beer logos and burping. Men will discover that women can also be disgusting at an 8:45 a.m. lecture after a late night.

But one thing everyone should discover: the benefits of cleaning up. It's always good thing, even if it means wearing something your mother likes to see you in.
