Kim Kardashian and Kylie Jenner - We couldn't help but notice that the 18-year-old's birthday-party dress resembled her older sister's bachelorette-party dress. Kylie has been sporting very similar styles as her Selfie Queen sis, but there's no contest here. Her sequined Nicolas Jebran mini can’t touch Kim's $20K beaded Balmain beauty. By Jazmine A.
