A black pencil skirt would definitely be on my list of top ten work essentials. It's a classic piece that you can pretty much pair with any top. I last wore it here on the blog with tights and a gold belt in winter. Side note: it really looks like spring in our apartment courtyard, loving all the tulips and blooms!
