Kendall Jenner is making quite a mark in the modeling world, and walked in Marc Jacobs' show this year for New York Fashion Week. The 18-year-old celebutante has been signed to The Society Management since November, which also represents Liu Wen and Adriana Lima. Prior to that, she worked with Wilhemina.

Wearing neutral colors, powdered eyebrows and a bobbed wig, Jenner looked every bit the high-fashion model. Her sheer top left little to the imagination, but the young reality TV star did not look nervous at all while flaunting her body in one of the biggest catwalks during the Mercedes-Benz Fashion Week Fall/Winter 2014 shows. 

Half-sister Khloe Kardashian was extremely proud of her little sister, posting a picture on Instagram of her during the show, in addition to close-ups of her makeup. “My baby sister killed it today walking in the Marc Jacobs fashion show!!! Kenny you are so dope to me!!! Congrats my baby!!! #NYFW #MarcJacobs #ProudSis.,”she wrote. Interestingly enough, she later deleted the provocative photo collage, replacing it with just a picture of Kendall's hair and makeup from the show.

While Jenner’s topless shirt raised some eyebrows due to her young age, this is not the first time she has pushed the envelope for fashion. In November, Kardashian had to stand up for Jenner after the model posted a racy photo from a recent shoot with Australian photographer Russell James.

She showed off her braless chest in a sheer black top. Kardashian, 29, stood up for her, saying to critics, "I love seeing all of these haters' comments. Naomi [Campbell], Kate [Moss], Cindy [Crawford]...All fabulous models...Models and photographers take beautiful artistic images. And I don't hear you birds chirp then. Sit down and enjoy the view! #SorryNotSorry."
