All black everything. Or all blue everything. Or all white everything. Whatever the color, the plan is to wear it from head to toe. That seems to be the memo celebs have been reading over the past few days. From the runways of Paris, where Janet Jackson was spotted wearing black on black, to Kelly Rowland's vision in white, it was the season to be monotone. Join the fun by layering on a single hue from sweater to shoe. Keep it chic and classic with blacks or navys, or punch it up with brighter hues, just like some of the celebs here.
