Random ramble ahead..
For some odd reason I feel like I should buy work pants..
My only pair of pants (started out writing paInts - Freudian slip much?) that I wear currently are a pair of distressed Levi's. I don't really like wearing pants and I can dress perfectly appropriate wearing a dress or a skirt. I do have some tops that don't get a lot of wear since I am mostly wearing dresses and they dont go well with the few skirts I have, but still I suppose that getting a skirt or simply stop buying separates would be a better option.
I definitely think you should buy work plants. They make work more fun
