Kendall, 18, walked in the Marc Jacobs runway show on Thursday during New York Fashion Week in a sheer v-neck tan shirt that showed her breasts. Kendall's racy look sparked criticism, but Khloe won't let any haters bring the model down.
"Its a fashion show. She doesn't choose! #Clueless," Khloe, 29, tweeted to a follower yesterday who said Kendall "needs to cover up" and doesn't "need to dress like that."
"She's too dope for you 2 understand! Yall would trade places with her in a second! The hate is real! Lol bye haters! #ModelLife #Simple," Khloe continued. "Basic b---hes NOT wanted."
"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 #SorryNotSorry," Khloe wrote.
Prior to her self-described "rant," Khloe expressed support for Kendall after she worked the runway.
"My baby sister killed it today walking in the Marc Jacobs fashion show!!! Kenny you are so dope...," she tweeted.
The fashion show was held at Lexington Avenue Armory, and Kendall's appearance was barely recognizable. She bleached her eyebrows, sported a chin-length straight haircut and wore a headband. Kendall's ensemble featured all nude colors.
Like Khloe, Kim Kardashian also tweeted to Kendall's success as a model.
"Proudest sister ever!!!! @kendalljenner I love watching you live your dream! #MarcJacobs #NYFW," Kim wrote.
Khloe previously defended Kendall when she was photographed in November wearing a black sheer shirt that also bared her breasts. Kardashian raved that's part of the high fashion industry and insisted her stepsister needed to "show them how its done."
