The singer greeting her fans outside our studio monday, wearing this white-hot ensemble. The look, all part of lady gaga's giant launch of her new single, "applause," after a broken hip kept her from performing for seven months. Twitter was on fire. The white dress was the best today, one person wrote. Another tweeting, she looked ab fab in her dress and caddie. The designer of that look, 22-year-old mathieu mirano. He's one of the youngest and brightest stars. And he created it from one of the most unlikely materials. It's paper. Reporter: That's right. The dress, the bra, everything down to the gloves. She was wearing paper panties. Reporter: This is what gaga's dress is made out of? Yes, it is. There was a special strong paper that we really wanted to use. And that works best for the ensemble. You can't rip this paper. Which is why we chose it for her because it's so resistant to how much pressure can be put on it. Reporter: How long did it take to make it.

We found somebody else. Scottie. Scottie. This is why she used a designer and paper that doesn't tear and didn't get her dress from "gma." What happens if she gets caught in the rain? It has a coating on top of it. It was -- not that I was tearing at the dress or anything. But the gloves were made out of the same thing. You could feel that there's almost a water-proof coating of it. A dress made out of meat. And a dress made out of paper. And I asked her about the VMAs. She said, I've been thinking about it for a year. Want to thank liz from props. I want to ask you, scottie, to put it down.
