It's no secret those Hills girls have style. And since we've always been a fan of their ready-to-wear looks (Whitney's cute work tunics! Audrina's edgy biker pants!  Stephanie's never-ending arsenal of print dresses!), we're totally confident that Lauren, Heidi and the rest of the gang would bring it in a Battle of the Best-Dressed. Fortunately, they've already got their first fashion faceoff! Turns out, our girls are up against those kutesy Kardashian sibs -- and the skinny-minis on 90210 --  for the 2008 People's Choice "Hollywood Style" award.

So whether you're on Team Heidiwood, or you're all about the (best-selling!) Lauren Conrad Collection, head over to the People's Choice Awards website and support your Hills gals.

The polls are open from now until October 3rd, so vote early and vote often! Who knows -- it just might be the second most important ballot you'll cast this fall...
