My most pressing wardrobe gap right now -- and the only one I can afford to close for quite some time -- is a pair of black pants in an of-the-moment silhouette. My strong preference for this would be for a great pair of boot cuts. Why black? Because I have blue jeans already, and black would go fabulously well with the majority of my wardrobe.I'm NOT after classic dress pants, you understand, just a pair of black boot cuts or flares that will work well in smart casual settings or that can be dressed up as needed (my office lends itself to both). What is the best fabrication to pursue for these pants? Would black denim get the job done, or does that send out the wrong vibe? Black stretch twill would be ideal, but such fabric is very hard to find in my size.

I welcome any and all thoughts!
