I have a sky blue pinstripe blouse that is incredibly flattering, though it's falling apart a bit around the cuffs (that's easy to hide, though). That goes on over a black skirt with just a little swish to it.

For shoes I dig out my one pair of heels, fairly low closed-toe numbers with ankle straps, in soft leather the color of peanut butter. They're beautiful, they're so comfortable I could run in them, and they cost me two dollars. They also perfectly complement the blue of the shirt, and the contrast between the black skirt and my impossibly pale legs makes me look like I really know what I'm doing when it comes to fashion, at least.
