Kendall Jenner may appear to have it all together, but her Met Gala look is literally hanging by a thread. "The entire gown is made from one piece of string," says Julia Haart, the La Perla creative director making the model's dress. "It's a very strong, very flexible, incredibly thin piece of nylon, and we've strung 85,000 crystals onto it. "Aside from her underwear"—a hand-painted black bodice—"that's it."

Making the gown took artisans in five cities (Milan, Bologna, Los Angeles, Rome, and New York), plus industrial and chemical engineers. "When I described a one-string gown to my team, I was told it's not possible," Haart laughs. "Of course, that just made me want to do it more."
