Lauren Conrad at Yigal Azrouel Charity Fashion Show Pictures

Lauren Conrad was decked out in a cute party dress for last night's Autumn Party and Yigal Azrouel fashion show to benefit the Children's Institute in LA. LC pulled back her darker hair, which she debuted arriving back at LAX over the weekend, for the event. Lauren is not afraid to experiment with beauty, and she's been a go-to source for her California-girl look since her days on The Hills, which is why her newest venture seems like the perfect fit. LC is writing Lauren Conrad Beauty, a book full of the tips and tricks she's learned over the years in the same vein as Lauren Conrad Style, which came out last year. Even though she's busy with her many fashion, beauty, and lifestyle projects, Lauren still makes time for fun. She's going strong with DWTS's Derek Hough, and the two have been spotted enjoying nights out around the city for the past few weeks.
