It was the fashion event that eco-conscious stars — and bargain hunters alike — had been waiting for. And at last night’s launch of Target’s latest designer collaboration, the organic Rogan for Target collection, everyone from Rachel Bilson to Felicity Huffman and Joy Bryant made sure they headed to Barneys New York in Beverly Hills to get a sneak peek. And One Tree Hill star Sophia Bush for one couldn’t have been happier. “I came here to check out the line because I really love Rogan as a line. And I love that they are doing a line for Target,” she told PEOPLE. “Sarah Jessica Parker said, ‘Fashion is not a luxury.’ It should be something that everyone should get to enjoy.” Get ready to enjoy it yourself this Monday when the collection of over 60 wardrobe staples of 100% organic cotton, priced between $15 and $45, hits Target stores and Target.com.
