As New Yorkers settle back into the swing of things post-Irene, thoughts return once again to Fashion Week. But along with, and because of, the hurricane’s unwelcome visit comes the irksome news that Marc Jacobs has had to push back his main collection by an unprecedented three days, from September 12 to 15.

The silver lining: Jacobs’ show, which will now close Fashion Week, makes for a serendipitous occasion to honor a major milestone, the 25th anniversary of the designer’s first namesake collection in 1986. Jacobs’ show has always been a must-experience, season after season, and not even a hundred-year storm can change that.

Another show that’s been rescheduled due to Irene’s churlishness is Theysken’s Theory. But the Olivier Theyskens is nothing if not uncannily persistent, delaying his show by only a day. And so here, too, the show must and will go on.
