I was in the minority - I brought about 90% of my clothes (then again, I was going from GA to PA and was worried about weather and all that, and I wasn't able to go home to get more when I needed them).
I can say that personally, I love having so many clothes, not because I have a ton of options but because I never have to do laundry. It stinks having to do it a lot when you have to pay for it.
Also, it wasn't hard to store all my clothes. I have a closet full (using magic hangers too, highly suggested), one small shoe rack (9 pairs), 2 drawers full (one of out of season clothes, and one of undies/workout clothes/oversized shirts), and one drawer for accessories (scarves, mittens, hats, etc). It sounds like a lot, but really, it wasn't.
Depending on how often you go home, you can obviously do without the out of season items and whatnot, but I didn't get to
Hopefully this helps!
PS - A lot of my friends who didn't bring as much ended up buying a lot more while at college. The only thing that I had to buy was a large heavy jacket (because obviously, I didn't have one, coming from GA), but a lot of my friends had to buy things that they had left at home, or extra shirts, the like.
