ABC News' Linzie Janis and Alison Kenworthy report:

Lady Gaga's world premiere of "Applause" Monday on "Good Morning America" sent social media into a frenzy, but the debut of her new single wasn't the only thing that had people buzzing.

Her white hot ensemble she unveiled as she emerged from a classic black Cadillac Eldorado to greet fans outside the 'GMA' studio was also turning heads, and as it turns out, for good reason.

"It's paper," the 22-year-old designer of the dress, Mathieu Mirano, told ABC News.

The dress, the bra, everything down to the gloves was made of paper.

"She was even wearing paper panties," Mirano explained. "We found that there was a special strong paper that we really wanted to use that worked best for the ensemble. You actually can't rip this paper, which is why we chose it for her. It's so resistant to how much pressure can be put on it."

Twitter was on fire with comments about the short, angled, crisp white paper dress.

"The white dress was the best today!!!!!!," one person wrote, and another tweeting, "She looked ab fab in her dress & caddy."

The dress took more than 100 hours to create from concept to execution with all the planning involved.

Mirano also created some of the outfits in the video for Gaga's new single, "Applause."

"We did the three bras that were made out of duct tape and safety pins that she's wearing kind of as a necklace," the young fashion designer said. "It's a harness of sorts. We made those with our own hands three days before the video shoot."

Gaga's music video for her new single has racked up roughly 5 million views in just 24 hours.
