After winning the fourth season of Project Runway, Christian Siriano has taken the fashion world by storm. From Rihanna to Demi Lovato to Lizzo and Billy Porter, he has dressed every age, shape, and gender. His designs are not only worn on the red carpet but are also accessible to the public.

His inclusivity is why he is one of the most high in-demand designers. Even on the runway, he makes sure to feature diverse models of various racial backgrounds and sizes, even flying in plus-size models to Paris for his show.

For the Fall/Winter 2020 collection, Siriano was inspired by the new DC film “Birds of Prey” and the world of surrealism. Coated in pink, the runway featured white hand sculptures and cut-outs of faces. Models wore pink and blue ponytails and a small black heart on their cheeks.

We went backstage and talked with the designer on the importance of inclusivity and the inspiration behind his new collection.

Runways are notoriously fashionably late. The venue at Spring Studios was packed with guests and celebrity attendees.

People mingled and took photos on the runway before the show began.

E! News reporter Zanna Roberts Rassi was there to cover the show.

There was even someone responsible for keeping the runway spotless in the middle of the chaos.

Meanwhile, backstage was a frenzy of make-up, press, and models rushing to rehearsal.

It takes a village to get picture-perfect. The look tonight was smokey eyes and pink lips.

Photographers were taking beauty shots to show the hot make-up trends for the season.

Beauty shots are uploaded immediately by the photographers for the magazines to blast across social media and articles as the show goes on.

Pink and blue ponytails, inspired by "Birds of Prey's" Harley Quinn, were a key element to the runway look.

The make-up was inspired by Harley Quinn as well, including her signature heart-shaped beauty mark.

Models were waiting to get into their fittings right before the show began.

The collection had a lot of shiny materials. "Everything looks liquid or wet or iridescent -- all the fabrics with light really come to life," Siriano told Insider.

The real celebrities were hard to spot because of the swarm of fans and security surrounding them –– until they sat down, seconds before the show.

Siriano this season was all about punk-rock vibes with a touch of glam.

Chokers and chains were the perfect accessories for this theme.

Typically, men don't walk the February NYFW shows but Siriano included men in this collection, which was a delightful surprise.

He even included multiple plus-size models of various body shapes, which is rare on the catwalk.

"I was showing my first show in Paris and there's no curvy models at all in Paris and that doesn't make sense to me," said Siriano. "So now I do it to show people because it's not fair."

Many of the silhouettes were recognizable –– it was the textures and colors that really made the pieces stand out.

Siriano played-up the dreamy, fantasy world theme with big silhouettes and whimsical patterns.

As the show progressed, the designs got more surreal and less ready-to-wear.

Coco Rocha, a model known for her posing prowess, was the star of the show. Her friends and family cheered her on as she went down the runway in an all-black look.

Siriano focused on a wide range of looks. "We have everything from a slip-dress to a suit to this amazing sculptural moment."

Coco Rocha closed the show with her signature pose.

When we asked what his plans after the show is over are, Siriano said, "Just to rest. I'm really excited we're just keeping it going because we read things everyday about what's happening in this business so that's it!" Considering the tumultuous nature of the fashion industry, releasing a new collection is all that a successful designer could hope for.
