Zac Posen is a man with many muses. Posen dialed up a few of his besties—girl-about-town Annabelle Dexter-Jones, the Like drummer Tennessee Thomas, avant-garde jeweler (and Z Spoke accessories designer) Yaz Bukey, writer Stephanie LaCava, and model Laura Love—to pose for the Z Spoke Spring lookbook. This mixed bag of mannequins was fitting for a somewhat sprawling collection. There were funky Lurex floral sweaters ("I'm mad for these," says Posen) that were a nod to the Warhol sixties, plus gauzy pinstripe shirtdresses for a twenties vibe ("nothing says Gatsby more than seersucker") and even an allover-sequin, bell-shaped number that got Posen chatting about Bob Fosse and Kay Thompson in Funny Face. "We're living in a period in fashion that is multi-referential. Anything goes," Posen says. "I want my clothes to relate to different people and their different moods." What held this lineup together was that it was all distinctly Zac. So the pretty young thing looking for a signature party dress will find one of those here, priced to sell at around $495, the line's average price point. But she'll also find modern iPad cases that double as clutch bags and sharp suiting separates that are a rarity on his eveningwear-centric runways.
