Look through fashion magazines, not for what EXACTLY to wear, but for trends. What colors are new this year, what lengths and shapes are skirts and pants, what textures are hot this year. I bet you can find some new ways to wear some old clothes by updating just a smidge. Then go through your closet like what was mentioned early in this thread. That's terrific advice, by the way.

But don't go TOO fashiony. Some of those magazines are so out there you can't figure out WHAT they're trying to tell you.
