A pleated skirt can make a classy work skirt. This Rebecca Taylor Women's Faux Leather Pleat Skirt is even more appealing because of the faux leather. The black skirt would look best with any color top and the blue skirt would look best with a white work top, tucked in. A pleated skirt also looks great with a popover top.
Pumps can be worn matching the color of the top with the black faux leather skirt and blue pumps with the blue skirt.
