Herve Leger dresses have been everywhere this past year. Take a look:
Hayden Panettiere,
Minka Kelly,
Rachel Bilson (we could have done without the clutch) and
Cate Blanchett all look fabulous in their Leger dresses. They knew which color to select for their skin tones and hair color and what neckline and length to go with for their body type. They also all paired their dresses with minimal jewelry
(or no jewelry at all) and the perfect pair of shoes to go along with the dress. This is Leger done right. It's very sexy, yes, but also sophisticated.

Mandy Moore, Kate Bosworth, Amanda Bynes and Vanessa Minnilo also all did good jobs picking out the perfect color for themselves, but none of them hit it out of the park quite like the previous four did. Still, all the dresses fit well and they all look great.

Now for the bad news. These dresses can be tricky to pull off. Here are some of the not-so-great Leger looks:
Victoria Beckham, Sophia Bush (we usually love her look we're just not a fan of this color combo), Audrina Patridge, Christina Aguilera (Amanda's smaller bust worked in her favor for this blue Herve dress), Heidi Montag (on the bad list because the shoes are a miss and Vanessa just looked so much better in this color), and especially Lindsay Lohan (Lindsay and Posh tie for the worst Leger look).
