Kim Kardashian's little sister, Kendall Jenner, only signed with Society Management in November, but she's already making great strides in the fashion world by walking in the Marc Jacobs show on Thursday.

The 18-year-old model strutted down the catwalk in a completely sheer top that exposed her breasts, barely-there eyebrows and an auburn wig.

It wasn't exactly her New York Fashion Week debut, as she has walked in the Heart Truth show last season, according to Fashionista, but this gig was an important one. She walked for one of the most in-demand designer, in one of the most hyped about shows.

Earlier in the week, Jenner shared a small clue in the form of a picture on her Instagram. She was "Kickin' it with @kegrand," who is a friend and stylist of Marc Jacobs.

Her fashion cred also includes posing for Russell James in a mesh shirt, and she also went topless for W magazine, in an outfit that's very similar to one Kim Kardashian shared last week.

Speaking of her older sister, it has taken Kim Kardashian quite a while to be accepted by the fashion crowd.

For years, Vogue's Editor-in-Chief Anna Wintour said that Kim Kardashian would never attend the Met Ball. She finally lifted that ban last year after being persuaded by Kanye West. But she said that "one Kardashian was enough" and didn't let her mother attend, according to the Daily Mail.

Even though Wintour was said to pick Kim Kardashian's dress, she was cropped out of a picture that named fiancé Kanye West one of the best dressed of the night.

Kim Kardashian is now rumored to be getting her very own Vogue cover, something that the EIC said would happen over her dead body. This is after much campaigning on the part of Kanye West.

Meanwhile, Kendall Jenner is getting a lot of attention for yesterday, some of it negative. Some criticized her for dressing "like that," according to the NY Daily News.

Older sister Khloe Kardashian took to Twitter to defend her. "It's a fashion show. She doesn't choose! #Clueless," she said.

She also added, "She's too dope for you 2 understand! Yall would trade places with her in a second! The hate is real! Lol bye haters!"
