Valentino was the designer of the night at the 2010 Vanity Fair Party in LA.

My favourite was Kate Bosworth who was a stunning vision in red.

The ruffles on her one-shoulder Valentino Pre-Fall 2010 gown were slightly flat, but I think stops her from being overwhelmed in this big gown.

Her hair was swept to the side whilst she opted for a pink lip colour to complete this stunning look

It looks like the parties are as well dressed as the main event.

Amanda Seyfried changed out of her Armani Prive gown, to this edgy Valentino Spring 2010 Couture look for the 2010 Vanity Fair party.

Her green couture dress appears to be made out of strips of leather which she matches with green earrings.

I’m not sure if it’s the light, but I prefer the darker runway version of this look.

Her look was complete with a silver metal Ferragamo clutch with rhinestone details and a pair of bronze sequin Ferragamo booties with metal heel.

I love how Amanda went from princess to diva from one event to the next.

Jessica Seinfeld arrived wearing a Valentino Resort 2010 beige knit dress.

The dress was trimmed with feathers both on the neckline and hem.

Nice dress, but I preferred the strappy runway heels.
