This may not be the first time Emma Stone has stepped out in a Lanvin LRD (remember her plastic-flower-embellished number at last year's Met Gala?), but her stunning strapless dress at last night's LA premiere of Gangster Squad sealed the deal on her status as both a red-carpet queen and a fashion darling. The actress chose a red woven silk and brocade sweetheart-neckline Pre-Fall 2013 dress — she's the first to step out in the latest collection — which she accented with rich Lanvin costume jewels. We love that the oversize crystal necklace played up her bare décolletage, but never took away from the overtly feminine silhouette. Elsewhere, she let the crystal flower brooch make a waist-cinching statement (no explanation needed there). To finish, she added a Lanvin rectangle clutch and matching Christian Louboutin Pigalle heels. If we learned anything from her impressive Amazing Spider-Man promo tour, it's that Emma is fearless where premiere style is concerned. And since this is the first "stop" on the Gangster Squad circuit, we're excited to see what's next from the (currently) blond beauty. Here's an all-angles look at her opulent Lanvin ensemble, right this way.
