Kylie Jenner
One might think having a newly-turned, mega-successful high-fashion model as a sister could be tough, but Kylie Jenner didn't let Kendall's spotlight affect her own style journey. The younger sibling added a whole new element to her wardrobe this year, deviating from the teenage rocker vibe and shifting into the style of a more elegant, refined young woman. That said, she still maintains her youthful and edgy side, but when it comes to formal dressing, there is definitely a noticeably more sophisticated flair to her choices.
