New York Fashion Week : Zac Posen, Thakoon tire out while Peter Som gets his second wind

With lackluster collections from Jason Wu, Thakoon Panichgul and Zac Posen, I was beginning to worry that New York Fashion Week was experiencing a young designer burnout.It's easy to see how it could happen, with the pressure to make headlines and reinvent season after season -- and now in the pre-seasons, too.But not every designer has the boundless imagination to be an Alexander McQueen.
