Kylie Jenner revealed a different look Kendall Jenner could've worn to the 2023 Met Gala in a new video

• Kylie Jenner shared a YouTube video about the 2023 Met Gala on Friday.
• It included a clip of Kendall Jenner trying on an outfit that was different from what she wore to the gala.

Kylie Jenner gave her fans an inside look at what it takes to prepare for the Met Gala — and shared a glimpse of a different outfit her sister Kendall Jenner could've worn on fashion's biggest night.

Kylie, 25, posted a video to YouTube on Friday that documented her journey getting ready for the 2023 Met Gala, which celebrated the late designer Karl Lagerfeld's career.

It included clips from nine days before the event, the day before, and the day of, showing both Kylie's Met Gala dress and after-party look in different stages of creation, as well as candid moments between Kylie and her daughter Stormi Webster.

Kylie attended the gala in a red dress designed by Haider Ackermann for Jean Paul Gaultier, which featured a train that doubled as a coat.

She changed into a black-and-white Ackermann design for an after-party.

As she shared in the video, her design team was torn on which dress she should wear on the red carpet until the day of the Met Gala.

In addition to the clips of herself, Kylie included a few shots in the video of her sister Kendall, who was also in fittings at the time.

Kendall, 27, was shown being fitted in a structured, white bodysuit that she didn't wear to the Met Gala or to an after-party.

In the video, stylists adjusted an oversized, ruffled hat on Kendall's head, which matched some detachable sleeves on her arms.

She stood in extremely tall platform boots in the video as well, which made Kylie look short next to her.

"This is crazy," Kylie said of Kendall's height in the boots. "And I'm a tall girl."

For the Met Gala, Kendall ended up wearing a black, sequin-covered bodysuit by Marc Jacobs with sleeves that doubled as a train, which she paired with coordinating platform boots.

And for an after-party, she changed into a sheer, sparkly jumpsuit with a thong over it from Nensi Dojaka.

The Kardashian-Jenner sisters have been frequent attendees of the Met Gala in recent years.

Kylie has attended five Met Galas, and Kendall has been to eight.

Of their sisters, Kim Kardashian has attended the most: She has been to every Met Gala since 2013.
