Storm Irene: Zac Posen Resort 2010.

Hana Soukupova

Zac Posen eschewed the forties-tinged Victoriana of his Fall collection to focus on more modern, real-world clothes.

Sessilee Lopez

It was a sensible move.

Jules Mordovets

Taking "clean shapes" as his MO, he touched on everything from simple yet sexy stretch canvas sheaths to tops and wrap skirts in mix-and-match floral prints to jersey button-downs and ruched satin pants in hard-candy colors.

Alana Zimmer

He displayed a similar restraint for evening, showing a white tux over a corseted wedding tank dress, as well as a dramatic smoking.

Tiiu Kuik

But Posen can't resist a little nighttime drama and neither can his fans, so there were plenty of party frocks, too.

Mia Rosing

The best, a strapless number in a subtle black and white tire print with chain detailing, took its cues from American couturier Pauline Trigère.
