Kylie is at it once again—this time with teen pop star, Mylie Cyrus. The "Locomotion" singer wore this crimson Pucci gown to the Cinema Against AIDS Gala earlier this year. She kept her look simple and elegant with a tiered necklace and loose up-do. Miley, who went bold with black, at the MTV VMA's last month, went for an edgier look, pairing hers with spiked accessories. Her new bleached blonde locks add flair and youth to this already daring ensemble. Her competitor is old enough to be her mother, but who do you think wore this sheer cut-out dress better?
