Lauren Conrad proves she knows a thing or two about style. Promoting her new book Lauren Conrad Style, the ex-Hills hottie wowed fans at a New York City book signing sporting a mini white Marchesa dress. Looking lovely in lace, it was her romantic hairstyle that added the finishing touch to this sophisticated look. Pulling her honey-hued locks back into a low loose bun, with soft face-framing tendrils, the crowning jewel was unmistakably the simple shimmering headband that held her do in place. The perfect way to add a touch of sparkle to your bridal look.
