Arriving with Selma Blair on one arm and Claire Danes on the other, designer Zac Posen was ready to kick off the 24 hour shopping party in midtown Manhattan celebrating his collaboration with Target. From Maggie Gyllenhaal, Mena Suvari, and Michelle Trachtenberg to reality stars Kelly Bensimon and Olivia Palermo, fashionable New Yorkers got the chance to shop the collection before it hits Target stores and on April 25. “This has been my goal since the beginning of my company, which was to create a brand that worked on a diversity of women’s body types and diversity of races,” he enthused.  “To affect real women’s lives [is] really just a visceral thing about women looking beautiful, feeling good, having an adventure, and being creative themselves.”  Pal Blair certainly thinks that Posen has achieved his goal.  “I feel so lucky that I know Zac and get to have it because this line would be sold out in an hour,” Selma told PEOPLE. “I mean, it’s amazing, I would wear all of it. I don’t view it as a lesser line.  I just view it as a more accessible line.”  The collection, which Posen says is inspired by “the best summer of a girl’s life,” features everything from casual, bright tops to a sleek suit combo, pleated skirts, and even iconic Posen brocade–-available as both a skirt and a dress. “His sensibility is young, it’s modern, it’s playful, it’s very New York,” said actress Ginnifer Goodwin. As for advice to dressing on a budget, Sex and the City stylist Patricia Field offered some wisdom: “Style doesn’t cost money–it just takes a little thought.”  Luckily, looks like Zac has done the thinking for us. Zac Posen for Target is available at Target stores nationwide and on April 25. –Shruti Dhalwala
