Kim Kardashian created a hoo-ha at the 2022 Met Gala when she admitted to going on a crash diet to fit into the Marilyn Monroe “Happy Birthday Mr. President” dress she wore to pose on the museum steps.

This year, however, she engaged in a different kind of body modification via the extreme corseting of the Maison Margiela by John Galliano couture dress she wore, cinched so tight at the waist it turned her figure into an hourglass version of the X Games. It was to tight, it was hard to imagine how she could breathe — let alone eat once inside the museum.

Viewers on social media immediately took notice. “Kim Kardashian honestly looks so uncomfortable and like she can barely move or even breathe,” posted one observer. “Fashion shouldn’t be like that.”

“Everyone is snatching their waist,” another wrote on X. “They said the one rule in the garden of time is no breathing, from Bad Bunny to Kim Kardashian.”

The corseting had been a feature of Mr. Galliano’s much ballyhooed January Margiela couture show, where it had been worn by both men and women, and where “making of” photographs on Mr. Galliano’s mood boards displayed the bruises left on the models’ flesh by the lacing. (Ms. Kardashian had been in the front row of that show.)

In the incarnation worn this time around by Ms. Kardashian, the corset was re-imagined in an antique silver brocade, and paired with a sheer silver metal skirt covered in lacy flowers, twigs, and mirror shards, to reflect the evening’s dress code, “The Garden of Time.” The idea of suffering for fashion, it turns out, is everlasting.
