Tips on what to wear for guys in high school?

I'm currently a sophomore in high school. You guys have any tips on what on what outfits I can wear to school? What shoes, shirt, socks, anything!

What I usually wear to school isn't that bad, but I think I can do better. I feel if I dressed a little nicer, it'd just boost my self esteem a little you know? Normally, I just wear cargo shorts and then some graphic tee. For shoes, I just wear nike running shoes. Yeah... I gotta work on the shoes.

So yeah any advice you guys have. Ideas on where to shop? Any websites or maybe other forums you can suggest? I wanna look kinda nice when going to school but I'm not rich and I don't need to look like a businessman.

Style is what you make out of it and as long as you feel comfortable in it who cares. If you want to "dress up" a bit try golf shirts instead of t's.
