Shot by Vanina Sorrenti, Lindsey Wixson styled the shoot for the Zac Posen Resort 2020 collection, picking the pieces she liked best from Posen’s extensive lineup. “It’s important to nurture aspiring talent,” the designer said, adding that he appreciated Wixson’s fresh perspective. “She put together separates and chose parts of the collection that I don’t regularly shoot, that I consider more ‘commercial,’ ” he explained.

The resulting lookbook has a freer, more whimsical aspect than usual. It’s evocative of a woman’s closet, with pieces chosen on impulse rather than strategically to tell a seasonal story. Wixson’s eclectic choices point up Posen’s broad range. There’s tailoring in a vaguely 1940s vein, strong-shouldered and full-legged. There are cotton frocks in crisp white and flirty Liberty florals. There are even interesting handknit sweaters, with drop shoulders shot through with Lurex.

As diverse as his offering is, Posen’s heart is in eveningwear. It was well on display at the Met Gala, where Jourdan Dunn and Nina Dobrev modeled innovative 3-D printed dresses made in collaboration with GE, like moving sculptures. Here, he focused on softer pieces, though they hardly lacked his signature drama. Wixson played up that aspect on the collection’s two standouts. The first was a Watteau-back cape gown in midnight ombré silk jacquard, both grand and easy at once; the second: a stricter, but still flamboyant evening coat in luscious peony pink silk moiré.
