Fashion Face-Off: Heather Graham vs. Kristin Cavallari

Heather Graham and Kristin Cavallari are never afraid to show some skin - when it comes to stirring up trouble or in a sexy cutout dress they both wore.

Both blonde bombshells left their locks loose and curly and kept their accessories simple for their ensemble, as you can see in the two images below.

While the actress who enjoys epic boink-a-thons picked black strappy heels to complete her look, Kristin Cavallari opted for nude peep-toe pumps.

It looks like Heather went with no underwear and the new Hills villain wore a flesh-colored coverup underneath, but, tough to say. We may never know.

On a side note, Kristin wore it to The Wizard of Oz exhibition at L.A.'s Fashion Institute of Design and Merchandising Tuesday night. Hills fans recall who used to attend that same institution: Lauren Conrad herself.

Anyway, who wore it better? Tell us below!

Who rocked this frock harder?
