It's official: Diane Kruger never gets it wrong. She pulls together the coolest kind of off-duty style one day, then shows off couture the next, with just as much ease. Arriving in Paris last night for the Jaeger-LeCoultre Place Vendome boutique opening, Kruger didn't just opt for the typical party dress — but slipped into a retro-inspired Jason Wu jumpsuit for the occasion. Sure, the style pro can wear just about anything, but truthfully, you can wear this one, too. Thanks to a form-fitting (but not too body-conscious) silhouette and a defined waistline, which a belt helps to accentuate, this fit is designed to flatter a woman's body and help shape and define curves. Add to that an open halter neckline — a secret weapon in elongating the frame — and it's a look that actually lends itself to a lot more body types than just Diane's, plus a wealth of special occasions. The only thing you need to finish off the look is a few of Kruger's key add-ons: a sexy heel, minaudière, and a hot red lip. Just shop our editors' picks below to get started.
