Jean-Paul Gaultier has become the first French fashion designer to sell his creations online, with the goods fetching prices that are about 15% higher than they would be at his super chic shop in Paris. The online boutique — at — is open 24 hours a day and delivers to 230 countries. It sells about 120 different articles, including silk ties and scarves, jewelry, handbags, sun glasses and other items that don’t need to be tried on. At least 20 top French designers are expected to join Gaultier on the Internet over the next two years, according to Celine Troadec of Marketing Process, creator of the mall-style Web site.
