Dressing up for the holidays is one of the greatest joys of the season but most of us don't have the money to overhaul our wardrobes. Fortunately, with a few key pieces, you can update things you already own and make them feel fresh and festive. First up, here's what to wear to that office holiday party. You probably already own a white blouse and black skirt. Try layering an inexpensive sequin tank (size up if necessary) over the blouse -- left casually unbuttoned, sleeves rolled up just a bit -- plus black tights and ankle boots for an entirely new look. Sophisticated yet glamorous -- and totally affordable!
