HarperCollins announced today that it has acquired rights to Lauren Conrad Style, a “4-color” fashion and style guide. The book, which will be published in fall 2010, will also include never-before-seen photos of the former star of MTV’s The Hills. “I am really excited to write a style guide,” Conrad said in a press release from HarperCollins. “I think fashion should be fun and reflective of who you are. When you wear clothes you feel good in, it shows in everything you do. I know this guide will offer simple, practical tips to help anyone look fabulous.” Last spring, HarperCollins published Conrad’s young-adult novel L.A. Candy, the first of a planned three-book series about a 19-year-old California girl who becomes a reality TV star. (Well, they say write what you know.) To date, the book has sold an impressive 166,000 copies, according to Nielsen BookScan, which tracks roughly 70 percent of retail book sales. The novel’s sequel, Sweet Little Lies, will hit stands Feb. 2, 2010.
