Photos of Rachel Bilson's Style and Red Carpet Events: See the Birthday Girl's Best Style Moments

It’s no secret that one of our major girl crushes is Rachel Bilson. As someone whose style is always amongst our top-ranked — whether she’s working a stunning Roberto Cavalli gown on the red carpet, perfecting the LWD, or mixing cool separates on the street, we constantly look to her for inspiration. Rachel has the ability to translate tricky runway trends into real-life and knows exactly what works for her petite frame (girl knows the leg-lengthening power of a nude heel, especially if it’s Brian Atwood!). And let's not forget it's her birthday today, so to celebrate, check out her style portfolio from her days as Summer Roberts on The O.C to today as one of the K-Meister's leading ladies!
