Kristin Cavallari's Style Evolution, From Cali Girl To Sleek Mom

From halter tops to floor-length gowns, this is a true transformation.

It seems like it was only yesterday when Kristin Cavallari made her debut on MTV's "Laguna Beach: The Real Orange County" as the sharp-tongued high schooler who the boys loved and girls loathed. You wouldn't even guess that the teen was born in Denver, CO, with her blonder-than-blonde lob haircut, crop tops and light-wash jeans that looked more like a California girl's uniform. But it was only a matter of time before Cavallari outgrew her "Hills" persona and wardrobe.

Now a wife and mom of three, Cavallari turns heads wearing her long bob with lived-in roots, sophisticated minidresses and sleek pointy-toe pumps. And it seems as though she's say goodbye to faux tans for good!

In celebration of Cavallari's 29th birthday on Jan. 5, we're taking a walk down memory lane with the reality star-turned-designer's style evolution. Keep scrolling down to check out her most memorable outfits.
