Two Harvard Business School graduates know exactly how expensive a wardrobe can be. So Jennifer Carter Fleiss & Jennifer Hyman established a new company called “Rent the Runway”. For just a fraction of the actual price, a woman can “rent” a high fashion gown for a weekend event. In the first month they’ve been in business, 20,000 women have already established accounts.  “Rent the Runway” is easy to use: you click on the gown you want and select the size and color. “Rent the Runway” ships it overnight to your front door. The dresses rent for $50 to $200. The gown is due back in 4 days. “Rent the Runway” pays for the shipping and dry cleaning costs.  One question: WHY DIDN’T I THINK OF THIS???
