It certainly isn't our relationship manifesto, but when it comes to daily dressing, two-timing is best. Dynamic, double-duty fashion and beauty scores are our newest obsession, nailing the best of the season's trends—from Gaga-like extremes to minimalism—all at once. Not only does it streamline our closets and bathrooms, but multi-faceted finds keep our bank accounts in tact—crucial for this time of year. Spiked, studded but still lady-like heels give business casual a rock'n'roll edge, and of-the-moment, compact make-up palettes are primed for the day-to-night transition. We don't normally advocate the killing of so many birds (unless of course, you can do it with one stone)!
