The US designer will show his spring/summer 2012 collection on September 11 at Lincoln Center's Avery Fisher Hall, a year after moving to Paris to show his eponymous collection in the French capital.
Zac - still presented his Z Spoke by Zac Posen diffusion line in his hometown - told WWD: "Paris is wonderful but it just feels like the right time to show in New York."
At the time of his move to Paris, the sartorialist said: "For the Zac Posen Collection, I wanted to give a different voice and focus in the international fashion arena. Obviously, New York has been extremely supportive of me and the stars were aligned to base Z Spoke in my hometown. I have learned over the past 10 years to trust my instinct, to have fun with experimentation and to innovate. I do not see this choice as a focus on Europe, rather, it's about taking a risk, which is something that is important to do as a creator in order to evolve."
