Audrina Patridge's Style Evolution: From Valley Girl To Hollywood Knockout (PHOTOS)

Audrina Patridge made her TV debut in 2005 as one of Lauren Conrad's sidekicks on MTV's hit reality show "The Hills." Since then, the California native has made a name for herself as one of Hollywood's sexiest starlets, modeling for men's magazines like FHM and Maxim and appearing in one of those scandalous Carl's Jr. ads. In 2010, she also donned many revealing outfits during her stint on Dancing With The Stars.

But the girl's not all sex appeal. In fact, she's got a laid-back style that's completely cool and totally approachable. At red carpet events, she favors floaty feminine dresses in bold colors, while her street style look is all about skinny jeans and easy tanks and tees that flatter her enviable physique.

Take a look back at how Audrina's look has evolved over the years and vote on your favorite in the slideshow below.
