I had a similiar pair of those pants last fall and one thing I liked to do was wear fishnets under them w/ heels. I also wore them w/ cropped blazers and slightly oversized sweaters.
I also like the idea of wearing them w/ a plain white button up shirt and then having a realy bright shoe - like a blue or emerald green, etc.
i have a pant version similiar to those pants. I wear them with a peachy color turtleneck with a black cardigan that has a pretty bow ribbon belt and the buttons are crystals. I always get tons of compliments.
