Bust out the bling.

Kylie Jenner, 29, made a surprise debut at the Victoria’s Secret Fashion Show on Sunday, wearing the brand’s first Fantasy Bra since 2018 — and she made history in more ways than one.

Victoria’s Secret called the Jacob & Co. creation a “one-of-a-kind masterpiece,” and its $50 million price tag makes it the most valuable in the tradition’s history. That’s more than triple the $15 million Gisele Bündchen’s Red Hot Fantasy Bra (the previous record-holder) commanded in 2000.

Since 1996, Victoria’s Secret has commissioned a jewel-encrusted bra almost every year, typically worn by one of its top Angels. The tradition stalled when the show went on hiatus and was left out of the runway’s 2024 and 2025 comebacks.

The centerpiece of Jenner’s bra, a 75.54-carat Fancy Vivid yellow diamond, is worth $22 million on its own, per the jeweler. Another 4,409 diamonds, totaling 1,373 carats, make up the rest of the design, each hand-set in a custom 18-karat gold mount.

In all, 15 artisans spent more than 1,000 hours on the piece, which glinted on the runway with a fringe of diamonds that swung as Jenner walked.

“My vision,” founder Jacob Arabo told Vogue, “was to create a piece of high jewelry that could be worn as a bra. No fabric, only gold and diamonds.”

Getting the nearly four-pound piece to sit right on Kylie took some trial and error.

“Even with exact measurements, what looks good on paper doesn’t always work the same way on the body,” Arabo said.

Victoria’s Secret chief creative officer Adam Selman told the outlet that fans clamored for the bra’s return after last year’s show. As for handing it to the reality star over a career model, he explained, “We’re going to put it on an unexpected talent who has a massive following and massive cultural impact.”

Boyfriend Timothée Chalamet, mom Kris Jenner and her longtime love, Corey Gamble, cheered from the audience at Sony Pictures Studios in Culver City, California. Sister Kendall Jenner, who walked the show in 2015, 2016 and 2018, wasn’t part of this year’s lineup.

“Best Day Ever,” Kylie wrote in all-caps over a photo of her diamond-clad torso on Instagram Story.

“My angel girl!!! 🪽🤍 So proud of you,” Kris captioned a celebratory post following the show.

Kylie joins a sparkly sorority led by Heidi Klum and Adriana Lima, who have each worn versions of the bra three times.

Klum, who modeled 2003’s $11 million version, later revealed she was four months pregnant with daughter Leni at the time.

Price tags dipped over the following decade, with Adriana Lima in a $2 million Damiani design in 2010 and Elsa Hosk closing out the era in a $1 million Swarovski collaboration in 2018.
