I'm all about getting more bang for your buck. Why not invest in something that can be worn an infinite number of ways? Donna Karan's The Infinity Dress ($895) is one of those pieces you want to have in your closet. Just look below to see the fabulous things it can do. Yes, it's pricey, but when you consider that it can be worn at least 10 ways, it's not so bad. It also comes in red and pink, though black is sleekest. I can't choose a favorite — each one is more stylish than the last. And the jersey fabric means it's super comfortable, too.
