Lauren Conrad making the cover of Cosmopolitan's new October issue is a big milestone — it's her THIRD TIME on the cover of the glossy! Lauren Conrad posed for the cover once a year for the past three years, and we have to say, this new one is our favorite yet. The Hills star's first appearance was in November 2008, when she wore a black zip-front tank and black jeans. This look seemed too plain for her signature girly, California style, but that's just us. Months later Lauren Conrad ended up on the cover again — this time in a white dress — for the July 2009 issue. This one was more exciting, and we loved the turquoise bracelet she wore to add color. But for the latest October 2010 cover — an important look because the now 24-year-old is promoting her new book about style (due out next month!) — Lauren Conrad wore a pretty patterned dress in vibrant red, pink, and purple by Zac Posen. You can definitely see how her style has evolved ... for the better!
