Labor Day, Schmabor Day! Celebrities have decidedly dumped your grandmother's fashion rules and are working white well past the traditional seasonal benchmark. From New York, where Milla Jovovich donned white lace at Stone, to the City of Lights, where Olivia Palermo opted for sheer cleanliness at Paris Fashion Week, Hollywood starlets are proving to be rebels with a cause.

What's the cause exactly? Our guess: lightness. Let's face it, we're all just a little weighed down by the state of the world lately. And while we could get all Sicilian and don our best funereal threads, celebs like Leigh Lezark and Lauren Conrad—who both donned snowy florals this week—seem to have a better plan. After all, don't they look carefree and fresh? So what do you think: Are these ladies blazing trails or simply bucking the system?
