Sharapova Upgrades to Cole Haan

And now, a brief break from Fashion Week. Let's talk fashion ... and sports! With the US Open selling a record number of tickets, tennis apparel is seeing a boom. According to the National Sporting Goods Association, tennis gear sales are up and hitting a higher growth rate in popularity than any other sport, with an 18.7% increase in participation in 2007. And according to WWD, this growth -- especially in women's -- means increased gear and apparel sales in addition to more court time. Case in point: Maria Sharapova's new Cole Haan line (Cole Haan Sporting), announced on the heels of her grievous abandonment of the miniskirt. "Mixing fashion and sport is an important trend that we see now," says prexy Jim Seuss. The line, scheduled to hit stores in February, offers 40 casual pieces for women, and 30 for men.
