The 'Insta-famous' sons and daughters of New York's elite just made their fashion debut - here's what happened

Guests walked a red carpet in the lobby of Gotham Hall before the show began.

Socialites filed into the packed lobby to grab a drink before start time.

Gotham Hall is a massive space that can accommodate up to 900 people, and every seat was filled. Attendees spilled into the aisles during the show.

Jonathan Cheban, a former PR pro who's known as one of Kim Kardashian's close friends, was in attendance. "I'm here before I head off to the airport," he told Business Insider. "I've known Andrew for a long time — I'm so excited for him."

Actress Abigail Breslin opened the show in an all-black, fur-collared wrap jacket.

The show's soundtrack included throwbacks like Spice Girl's "Wannabe" and Crazy Town's "Butterfly." Here, Tiffany Trump makes her entrance.

Andrew has been my best friend since I was about 3 years old," Trump told Business Insider. "When he asked me to walk for his first fashion show, I had to say yes.

I love the idea behind having personalities in the show and not just normal models," Gaia Matisse, great-great-granddaughter of French painter Henri Matisse and daughter of the late pop artist Alain Jacquet, said to Business Insider. "The industry is changing, and showing the clothes in this different way is exciting and much more relatable to the people who will be buying them.

Kyra Kennedy, daughter of Robert F. Kennedy, Jr., was also happy to support Warren. "It was exciting and a great opportunity," she said.

In total, there were 25 different looks for the show. Here Reya Benitez, daughter of legendary Studio 54 DJ John "Jellybean" Benitez, makes her runway debut.

Kennedy and Matisse joined Warren as he took a bow on stage.

Emory Stewart said he was impressed by both the clothing line and the women who walked the runway. "They're amazing people of our generation — we're the kids that are churning it out," he told Business Insider.

As things wrapped up, Lance Bass of NSYNC fame took selfies with a few fans.

Many of the women, including Matisse and Benitez, made an appearance for interviews out on the red carpet after the show was over.

I hope to take Just Drew to the next level," Warren told Business Insider. "It started out as a fun project while I was in college, and now that I'm done I have been taking it so seriously, and want to continue taking it seriously.
