She wore Jacobs' cropped pants and a see-through top (you can see the NSFW version here), along with a blunt wig and bleached eyebrows.
"I just recently turned 18, so this [Marc Jacobs show] is my big kick-off to start and grow my career," Jenner told Into the Gloss backstage. "The New York fashion scene is crazy, madness, but I love the energy. I love everything about it -- like the hair and makeup today, it’s incredible. I’ve never had my eyebrows bleached; I don’t even look like myself!"
"I’m a little nervous for the show, but I’m really excited," she added. "It’s my first runway show, so I’ve been practicing. I feel like everybody has their own individual walk, and that’s what makes someone so special. Maybe I’ll run down the runway!"
