"Even though I'm always inspired by the sixties, it's important for me to stay modern," Lisa Perry said during a presentation at her Madison Avenue boutique. For Spring, that meant a new-for-the-designer print and formfitting dresses that stayed on the ladylike side of body-con. The print brought together this season's minimal, geometric color-blocking—a nod to Ellsworth Kelly—with galactic shapes like stars and moons, inspired, Perry said, by gazing up at the night sky from her beach house in North Haven, New York. Picked out in sequins, the colorful constellations also showed up on a cropped white jacket and a floor-grazing maxi dress.

The designer's signature A-line silhouettes guaranteed a thoroughly mod mood, as did the lineup's saturated and ultrabright hues. Next to all the twinkling stars, though, a simple white trapeze dress in lambskin leather was refreshingly simple. Current-day Edie Sedgwicks would be smart to snap one up.
