The September shows will now run from Sept. 5 to 12, but the CFDA is making a proactive decision and will be moving its dates to its desired schedule next year.
"We have...made the firm and final decision that, beginning in 2009 and continuing every year thereafter, New York will without hesitation start showing on the second Friday of February and the second Friday of September," according to the letter. In 2009, that means New York show dates will be Feb. 13 to 20 and Sept. 11 to 18, and, in 2010, Feb. 12 to 19 and Sept. 10 to 17.
Kolb said the CFDA needed to change the dates to accommodate the wishes of the American industry, from designers to retailers and editors.
"In the end, Diane and I decided that the extra two days this September would be more confusing, so we will continue to have the early start," he said. "Also, had we gone later, it would have squeezed London to a shorter period, based on Paris and Milan having set their dates already, so out of respect, we didn't go Sunday to Sunday."
Kolb said the letter was sent in the "spirit of cooperation."
"We remain interested in coming up with an international calendar that works for everyone," Kolb said. "And at the same time, we have the direction from our designers to start later. Unless Milan and Paris move back, this will create a situation for London that we are aware of. This is a year away, and each city has to look at the city before and after them when they schedule their dates."
Kolb said one possibility would be to consider scheduling "crossover dates," with the beginning and end of fashion weeks in each city earmarked for designers that are more relevant locally, for instance.
