Zac Posen: Spring 2012

Zac Posen made his return to New York Fashion Week with a hefty dose of drama and intrigue. Floor-sweeping gowns are Zac's specialty, but this season he's outdone himself, offering up impeccable tailoring, sexy corsets and boning, and lots of Old Hollywood glamour. Plunging necklines were equally matched by fishtail skirts, and ample textural details delivered high-impact silhouettes on every look, while Posen stuck to deep reds, blues, black — and then surprised with a pop of lively green. It's a collection begging to be worn on the red carpet. Just click through to see all the looks.
