Zac Posen recently announced that he will be designing for Target's Go International series of collections. Posen's Go International collection will be available at most Target stores nationwide and online from April 25, 2010 through May 30, 2010. Pictures and prices from the line are not yet available, but I will post more once I know more (the pictures above are from Posen's Spring 2010 collection).
On a side note, Posen also recently announced that he will be designing a less expensive line called Z-Spoke, which will be exclusively available at Saks Fifth Avenue. Z-Spoke will be available in the Spring of 2010 and prices in the line will range from $78 for a t-shirt to $675 for a dress.
