At a launch party in N.Y.C., Zac Posen celebrated his new Target collection with Claire Danes, Selma Blair, Maggie Gyllenhaal and Ginnifer Goodwin. Underneath glittering chandeliers and pink and silver balloons, partygoers sipped strawberry martinis and shopped the colorful collection, which is already a hit among Posen’s celebrity pals. “I can’t believe he created this [dress]. It’s $79,” Blair gushed. “If I was 16 right now, I’d be on top of the world. There are amazing little party dresses—perfect for summer cocktails or a night out.” Click on to hear what Goodwin and other stars love about Zac Posen for Target, and if you’re in N.Y.C., snag your favorite pieces before Posen’s Herald Square pop-up shop closes tonight at 11 p.m.
