On Sunday, Kylie posted an Instagram story of her older sister struggling to walk up the brick stairs leading to the ceremony venue because of her form-fitting gown.
In the video, Jenner is seen waddling up the steep steps wearing her dress — a blush floral gown featuring a fitted mermaid silhouette — which she teamed with sensible footwear, a pair of what appear to be Birkenstock clogs. Kylie is heard laughing in the clip and lamenting about how difficult the stairs are to navigate.
"S--t these stairs are crazy," she says.
Fans on the internet took note of the hilarious, yet realistic fashion blip. The video went viral on TikTok, some users reposting the clip while others making edits with audio sampling Jenner's famous lines including her "built like an athlete" quote.

In addition to the ceremony dress, the 818 Tequila founder served many looks throughout the wedding weekend in Portofino.
For the welcome dinner, Kendall wore a gothic Dolce & Gabbana dress designed with a satin bustier and frill-hemmed sheer skirt. She accessorized the look with an art deco cross necklace. She coordinated with her boyfriend and NBA player Devin Booker, who was dressed in a cool all-black outfit.
The next day, she wore a brown Dolce & Gabbana skirt suit decorated in a vintage-like floral pattern, which she paired with a classic bold red lip, for a sunny boat trip.
Earlier this month, Jenner also turned heads at the Met Gala as she attended the star-studded fashion event alongside all of her sisters and mom Kris Jenner (a Met first for the Kardashian-Jenner family).
To celebrate the institute's "In America: An Anthology of Fashion" theme and honor the night's Gilded Glamour dress code, the model wore a Prada two-piece ball gown that featured an extraordinary train designed with ruffles and a fishnet crop top. She added an edgy aesthetic with her bleached eyebrows and smokey eye makeup.
