The biggest stars get the newest dresses, which is why it's no surprise to see Les Miserables star Amanda Seyfried in one of the most stunning Pre Fall 2013 gowns we've seen so far. The fishtail, heavy fabric and structured strapless neckline give this one away instantly - it's Zac Posen, and we think Amanda looks incredible in it.

We know some of you are tired of the predictability of fishtail gowns for big award shows, but they create instant drama, the shape adds height to the often tiny actresses, and all those in-and-out curves make those tiny hollywood bodies look voluptuous even if they're not.

The choice of jewels (from Lorraine Schwartz) gives a slight unexpected edge to this look - so many stylists would have just put her in a big, blingy diamond necklace that sat above the dress - but with the long loose hair, the longer pendant just about works. Jimmy Choo 'Vibe' sandals apparently finish the look, not that you can see them under all that dress!
