You'd have to be living under a rock if you haven't heard of Kendall Jenner. The elder daughter of Bruce and Kris Jenner, she's the step sister of the famous Kardashian women. And if you've seen the show, you'd know, she's the most down-to-earth and humble of the Jenner/Kardashian clan, besides being one of the most famous models in the world, right now.

Insanely popular on social media, Kendall is also a renowned fashion icon, someone who's looked up to by millions of young women. Just search for #KendallJenner and you'd know what we're talking about!

She loves her blacks, greys and reds and you'll almost never see her without a jacket, a shrug or a trench coat (Psstt... she has a lot of them, of course).
