Hey-I've been asking that question too. But it really depends on what color shirt you are wearing, or the colors of your accesories. If you're wearing say a purple shirt with a pink scarf go with maybe a black and pink shoe (black almost always works :)). But next time-be more specific on what else your wearing too. Because then you'll get more specific answers :). Hope this helped-at least a little :).
Tan or gray shoes depending on what color your slacks or skirt is. I have no idea whether you are a man or woman.
