Talk about pushing the envelope.

As expected, Kendall Jenner, Gigi and Bella Hadid, Karlie Kloss, and more big names all walked the Marc Jacobs spring 2017 show at New York Fashion Week on Thursday, but they still managed to shock thanks to the designer's in-your-face choice of get-ups.

The models all wore multi-colored dreadlocks piled high on top of their heads along with bright ensembles -- complete with thigh-high socks and dangerously high platforms -- evocative of rave culture.

But it's 19-year-old Bella who had the raciest outfit by far, exposing her nipples in a sheer white dress underneath a bedazzled coat.

Thankfully, Bella proved to be a pro in her precarious heels, after taking a tumble at the Michael Kors spring 2017 runway show on Wednesday. Though after taking a closer look at the gigantic platforms the models were walking in on Thursday, we totally wouldn't have blamed her.

As always, mama Kris Jenner couldn't be prouder of her model daughter.

"Kendall, this is everything!!!!!" the momager tweeted on Thursday. "@kendalljenner walking for @marcjacobs today! #NYFW #marcjacobs #proudmama."

And despite all those big names, the dreadlocks were clearly the star of the show. The colorful hairstyle was inspired by the signature look of Matrix director Lana Wachowski, who also served as the face of the brand in January.

"This season's ad campaign represents a series of connected events; a visual narrative," Jacobs Instagrammed alongside a pic of 51-year-old Lana in January. "It is a personal diary of people who have and continue to inspire me and open my mind to different ways of seeing and thinking."

This season’s ad campaign represents a series of connected events; a visual narrative. It is a personal diary of people who have and continue to inspire me and open my mind to different ways of seeing and thinking. The spectrum of individuals photographed in our Spring/Summer 2016 ad campaign represent a celebration of my America. In collaboration with photographer David Sims and stylist Katie Grand, the people featured in our campaign personify this collection of fashion through their individuality. Collectively, they embody and celebrate the spirit and beauty of equality. It is with an overwhelmingly full heart that I share this first portrait of our Spring/Summer 2016 ad campaign. Lana Wachowski. I was first introduced to Lana via YouTube in December 2012. The speech Lana gave to accept the Human Rights Campaign, Visibility Award, (October 20, 2012) was utterly profound in its script and her articulate, brilliant and timeless delivery. She expressed thoughts and ideas that have filled my head and heart always but had never been so eloquently captured in language that was so tangible, intelligent, poignant and full of possibility. I found myself referencing Lana’s words in my daily life and sharing her speech with close friends. In the days before our Spring/Summer ‘16 fashion show and through a fateful series of communications, much to my incomprehensible delight, Lana accepted an invitation to our show in New York City and thus I took her, “fashion show virginity.” Lana’s ineffable beauty captured by David in this portrait reminds me of the personal sentiment she shared with me about, “learning you can make important friends at anytime in your life.”

As for the actual hair in the show, it was created by an Etsy seller named Jen from Palatka, Florida, who was approached by famed hair stylist Guido Palau. Jacobs sent a picture of Lana to Palau, who in turn spent weeks searching on the Internet for a seller who could provide her the hair in a variety of different colors, Palau tells New York magazine.

Jen and her daughter ended up hand dying over 12,500 yards of yarn in 300 different shades just for the show.

ET spoke to Lana's sister, 48-year-old Lilly Wachowski, in April at the GLAAD Media Awards, less than a month after she came out as a transgender woman. Lilly acknowledged how important the support is that she received from Lana, who herself came out as a transgender woman in 2012.

"Even the simple act of being. She pushed all these fence posts out and, so in a lot of ways, I was just following in her footsteps," Lilly said of her sister. "It was almost like she had her snowplow out and all these channels started opening up for me."

"I say, you have to be true to yourself," Lana herself told ET exclusively at the Jupiter Ascending premiere in February 2015. "When you encounter people, whether they're racists or they're homophobic or their transphobic, what you realize is that those people are actually more controlled by social convention than you are."

"In a way, once you accept who you are, you are will always be more free than they are," she continued.
