Kendall Jenner made her big modelling debut strutting down the runway of the New York Fashion Week in a sheer, chest-baring top by Marc Jacobs.

Kendall Jenner's nipple-bearing outfit may have been a little too much for some viewers as the "Keeping Up with the Kardashians" star soon became the target of backlash following the show.

Kendall Jenner's controversial top became the most the talked-about topic in various social media sites overnight, however not all of it was good.

Nobody was more proud of Kendall Jenner's first big catwalk show with Marc Jacobs than her sisters.

And nobody was fiercer in their defense of the 18-year-old reality star turned fashion model than Khloe Kardashian, who took to Twitter on Thursday evening to embark on an angry rant in response 'haters' of her younger sister's new gig.

The 29-year-old Keeping Up With The Kardashians star did not hold back as she slammed anyone who tried to tear down her beloved family member and castmate.

It was a big night for Kendall, whose dreams of a top modelling career became a reality when she marched down the runway at New York Fashion Week for famed designer Marc Jacobs.

The starlet looked very high fashion in a sheer, form-fitting V-neck sweatshirt which left nothing to the imagination, teamed with cropped two-tone trousers and military boots.

Her face was barely recognisable beneath the layers of makeup, and her lengthy tresses were replaced with a short futuristic wig.

It started off well, with Khloe overcome with pride as she shared an Instagram collage of Kendall out there on the catwalk for her first time.

'My baby sister killed it today walking in the Marc Jacobs fashion show!!!' she wrote alongside the image.

But the proud big sister soon became outraged as she began to take notice of the inevitable negativity from 'haters'.

And it seems that a protective, defensive rant was simply too hard for Khloe to resist.

One Twitter user seemed to be confused about the point of a fashion show, writing: 'OMG get a bra, no need to dress like a skank geez [sic]'
Khloe began blasting the online negativity the moment it began.

'She's too dope for you 2 understand! Y'all would trade places with her in a second! The hate is real! Lol bye haters!' she wrote, before quickly adding: 'Basic bitches NOT wanted.'

Kendall's proud big sister then wrote: 'Oops I keep forgetting I'm supposed to be on my 'don't sweat the small stuff' ish.... But I just can't pass up a good rant,' and added a sneaky Twitter meme hashtag: '#SorryNotSorry'

Khloe then responded directly to the same user that initially rained hell on her little sister, who insisted: 'we're not hating Khlo, she needs to cover up she doesn't need to dress like that [sic]'

But the reality star was not about to accept such ignorance with any grace, retorting: 'Its a fashion show. She doesn't choose! #Clueless'
