It goes without saying that the LBD is the quintessential party frock, so naturally we were drawn to this pic of actress Kate Bosworth rocking this ladylike design from Oscar de la Renta. It's simply stunning, and by that we mean it's stunning in its simplicity. The illusion neckline, the classic silhouette (so flattering, yes?), the waist-cinching belt... it's all so perfect. And speaking of perfection, how about that hair? It is so perfectly coiffed it looks photoshopped (and we mean that in the best way possible). Sleek and shiny, with just a hint of a Veronica Lake wave at the ends. It looks beautiful with her clean, fresh face and bold red lips. So polished and so pretty!
