And, in the case of Kim Kardashian West, nearly unbelievable proportions, too.
The "Keeping Up With the Kardashians" star arrived to the celebrated event dripping in crystals as part of a wet look created for her by the master of runway camp, Thierry Mugler.
But the impressive effect of her shiny silicone-and-organza dress, glossy hair and moist-looking makeup aren't what still has people buzzing two days later.
Instead, it's the emphasis that work of art put on her figure. And now, Kardashian West has revealed how she achieved that barely there waist in a video for Vogue.
Stuff We Love
Mugler, who's work for Kardashian West marked the first time he's designed for his House of Mugler in 20 years, enlisted famed corset maker Mr. Pearl to fit the star with a body-cinching undergarment.
Several sets of hands can be seen pulling the laces as tightly as possible as she prepared for the event in the clip.
"OK, Anna, if I don't sit down for dinner, now you know why," Kardashian West looked says in the video to the Met Gala chair and Vogue editor-in-chief Anna Wintour. "I can only half-sit."
Well, sort of half-sit.
The end result of all the trussing left standing as her best, and basically only, option. She even arrived in the gala in a van that allowed her to stand and secure herself to a pole on the way.
"I'll be walking around, mingling, talking," she said, mentioning her alternatives to sitting.
But she knew there was one more thing her tiny-waist transformation wouldn't allow her to do: use the bathroom.
"I won't be able to pee for about four hours, so we're coming up with a plan of what we do in case of an emergency," Kardashian West confesses in the video.
Of course, the corseted bodysuit wasn't the only thing responsible for her lean look. Kardashian had to forgo indulgences before to fashion's biggest night.
But not afterward!
"I am going to eat doughnuts tomorrow," the current Vogue cover star reveals. "I have a delivery at 8:30 in the morning for two dozen mini doughnuts."
