I think this is going to be the hardest ever poll, mostly because I’m not at all keen on the dress.

For the “Hangover” Dublin premiere last week, Heather Graham wore this black strapless Herve Leger dress, with sheer cut-out panels down oneside.

The actress completed her look with a black strappy sandals, and a matching clutch.

Kristin Cavallari obviously hadn’t been keep up with current events, because the very next day she wore the same dress to the “The Wizard of Oz” Exhibition Opening Night Gala in LA.

Kristin also kept her accessories to a minimum opting for a stack of gold bangles and nude platform slingbacks.

After agonizing over this for a long while, I will pick Kristin, mostly because of the black nude theme she has going on, and secondly because she looks like she actually put a comb through her hair.
