The flagship of your evening wardrobe, it turns out, can also be put to good use during working hours. The trick is to make it appropriate for the office with the right trimmings. A black suit jacket and black tights give you a sleek, polished look. Too dark? Take the edge off with a cardigan. Or how about a string of pearls and a leather belt? Either way, when the clock strikes five, your outfit transforms back into evening finery -- and none of your coworkers are the wiser!
