More designers are shuffling around between the fashion weeks. The latest is Zac Posen who will return to New York Fashion Week after spending the past two seasons showing in Paris. The designer will unveil his Spring/Summer 2012 collection at Lincoln Center's Avery Fisher Hall on September 11.

"Paris is wonderful but it just feels like the right time to show in New York," Posen said.
