Thursday (Feb. 13) the "Keeping Up With the Kardashians" star walked in a Marc Jacobs runway show for the 2014 New York Fashion Week, sporting a sheer top that leaves absolutely nothing to the imagination.

We do dig her brown crop pants, stylish purse and kicky boots, though.

Reactions were mixed. Kendall's sis Kim Kardashian writes on Instagram, " Proudest sister ever!!!! I love watching you live your dream!" and other big sis Khloe Kardashian echoes those sentiments with, " My baby sister killed it today walking in the Marc Jacobs fashion show!!! Kenny you are so dope to me!!! Congrats my baby!!! ... She's too dope for you 2 understand! Yall would trade places with her in a second! The hate is real! Lol bye haters!"

Fans on Twitter ranged from saying Kendall "killed it" to "
I'm not sure if Kendall Jenner or a topless alien just walked for Marc Jacobs" to people being more appalled by her hair and makeup than the nipple peep show.
