While Lo Bosworth's former "Hills" costar and fellow author, Whitney Port, has chosen to tour the country in bright, attention-grabbing outfits, it just wouldn't make sense for laid-back Lo to show up to book signings in the same type of red carpet numbers. Lo's always been that effortlessly chic Hillzie with a keen eye for style that doesn't go overboard, and that's why we've totally embraced her whimsical tops and jet-setting fashions.
+ Lo's jaunted all over the U.S. this year, speaking at local bookstores and signing copies for fans. What do you think of the budding writer's business casual wardrobe? Sound off in the comments!
