The Hills star Lauren Conrad appeared on the David Letterman show yesterday talking about her current work plans and her Spring clothing line. Lauren wore a pair of on-trend high waisted, wide-leg trousers with a pretty pale blouse. She balanced the delicate top with an edgy leather jacket for a chic ensemble. Lauren accessorised with the belt from the Sex and the City Movie and her trusty Chanel 2.55. What do you think of Lauren's style?
