Polo Ralph Lauren, the upmarket men's and women's retailer, is to unveil its e-commerce website this Friday, the first of the high-end design pack to claim a stake in e-tailing.The website will offer 2,500 styles under the Polo and Ralph Lauren brands and is the first offering from the Polo Ralph Lauren Media joint venture between the designer, NBC, and NBC partners ValueVision International and NBC Internet.Jeff Morgan, president and chief executive of Ralph Lauren Media, said that polo.com will be more than just a website. He intends that content from the site could serve as a springboard for other media projects, such as TV specials and magazine features.Morgan does not believe that the e-commerce venture will fit in well with other Polo Ralph Lauren channels: "We believe that the Internet will only increase our exposure, expanding our customer base for the Ralph Lauren brand," Morgan said. Top names will doubtless watch the launch with interest. Last year, Tommy Hilfiger unveiled an informational site, but hasn't yet announced the launch date for his e-commerce venture. Donna Karan is studying the concept, according to CEO John Idol, while Calvin Klein doesn't sell online.
