"What's the LPD?" Lisa Perry asks every time she develops a garment. The abbreviation stands for Lisa Perry Detail, and typically refers to one of the designer's mod signatures: the circle pocket, the A-line silhouette, the primary-color pop.

For Pre-Fall, Perry nicely incorporated an LPD into each and every piece, and her standby silhouettes were well-represented. The swing dress got a menswear-inspired update done in navy wool pinstripe with cherry red accents, while the best-selling collarless coat was rendered in a subtle gray windowpane check that reversed into a solid cerulean blue. The season's standout print was an architectural zigzag, inadvertently inspired by Philip Johnson's Gate of Europe towers. (Perry saw a photo of the buildings only after she had already developed the pattern.) It's not a surprising coincidence, given her voracious interest in modern art and architecture.

What was surprising—and more than welcome—were her more tomboyish ideas. A wool popover top and matching sweatpants, worn with a pair of white slip-ons, looked particularly cool. What's more, the top's circle pockets were the perfect LPD.
