U.S. reality TV star Kendall Jenner bared her breasts to the world on Thursday (13Feb14) as she walked the runway for the Marc Jacobs fashion show in a sheer top. The 18-year-old model made her debut for the acclaimed designer during the Mercedes-Benz Fashion Week in New York City, and turned heads in a revealing outfit. Jenner showed off Jacobs' Fall 2014 collection by donning bleached eyebrows, pale skin, brown bob and a skin-tight sheer shirt, baring her nipples. The teen's elder half-sister, Khloe Kardashian, took to Instagram.com to post a photograph of her star sibling, and defend her following negative comments from unapproving critics. Kardashian wrote, "My baby sister killed it today walking in the Marc Jacobs fashion show!!!... Congrats (sic) my baby!!! "She's too dope for you 2 (to) understand! Yall (sic) would trade places with her in a second! The hate is real! LOL (laugh out loud) bye haters!." She added, "Oops I keep forgetting I'm supposed to be on my 'Don't sweat the small stuff' But I just can't pass up a good rant... It's a fashion show. She doesn't choose! Clueless."
