A random fashion question.....

What do I wear at college?  I just posted about this over my other blog, Old-Fashioned Beauty.  More or less, with a dress code that calls for slacks or pants or khakis, and a collared shirt, I'm needing some suggestions on cute, inexpensive outfits!  I don't want a boring polo shirt here.  Blouses are almost a must so I can wear them with skirts too, vintage style preferred.  Sewing pattern ideas are accepted.  :)
