Lauren Conrad just launched her new line Paper Crown, and she teamed up with InStyle.com to give away one of her favorite pieces—the tiered chiffon Ella maxi, shown here. “I am in love with this dress,” Conrad told us. “It moves so beautifully and makes you feel beautiful, too!”  The reality-star-turned-fashion designer wore the look herself to a Los Angeles bash last month. “I have worn it as-is, and also belted the top layer with a silk tie to give it a little shape,” she explained. “The full tiers give this dress such a romantic look.” This look can be yours!
