TL;DR
Jacob & Co. created the most expensive Fantasy Bra ever made — a $50 million high-jewellery piece set with 4,410 diamonds around a 75.54-carat Fancy Vivid Yellow centrepiece. Kylie Jenner wore it for her Victoria's Secret runway debut in October 2026; we break down the piece and the record it set.
Some runway looks are worn. Others are engineered. On October 18, 2026, Kylie Jenner made her Victoria's Secret runway debut at the brand's fashion show in Culver City, California — wearing what Haute Living reports is the most expensive Fantasy Bra ever created: a $50 million high-jewellery construction by Jacob & Co., built from 4,410 natural diamonds — and not a single thread of fabric.
The headline number barely captures it. The piece contains 1,373.39 carats of diamonds in total, assembled by 15 artisans over more than 1,000 hours. And at its centre sits the stone that does most of the talking: a 75.54-carat radiant-cut Fancy Vivid Yellow diamond, graded VS2 in clarity by the Gemological Institute of America — reportedly worth around $22 million all on its own, per Baller Alert.
The most expensive Fantasy Bra in history
To understand why this bra costs $50 million — more than three times the previous record — look past the centrepiece. Flanking the yellow diamond, two round brilliant white diamonds totalling 11.85 carats sharpen the focal point, while the remaining stones sweep across the piece in an array of cuts that includes Jacob & Co.'s signature Angel-Cut. Everything is set in 18-karat white and yellow gold, and the finished bra weighs just under four pounds — roughly the weight of a small laptop, worn on the runway like lingerie.
Getting there was a manufacturing feat. The design breaks down into 3,218 individually engineered components, developed from an initial sketch through full-scale modelling and computer-aided design, then cast, hand-polished and assembled into a structure that flexes instead of sitting rigid. It's the difference between jewellery you display and jewellery you inhabit.
No fabric. Only gold and diamonds.
Here's the detail that stops jewellers in their tracks: there is no fabric base at all. Earlier Fantasy Bras were built on lingerie — fabric carrying the gemstone work. Jacob Arabo, the house's founder, threw that formula out. "My vision was to create a piece of high jewelry that could be worn as a bra," he told Vogue. "No fabric, only gold and diamonds."
To make an all-metal, all-diamond garment move with a body, the team drew on Jacob & Co.'s Rare Touch jewellery collection, which the house describes as an exploration of how precious metal can be shaped to move like fabric. The result is high jewellery with lingerie's job description: it has to flex, drape and survive a runway walk — which may be the most demanding brief in the business.
Why are fancy vivid yellow diamonds so expensive?
Start with the chemistry — or rather, the trace of it. The yellow in a diamond comes from nitrogen atoms trapped in the crystal lattice as the stone formed, and the depth of the yellow depends entirely on how much nitrogen got caught inside. Stones with only a whisper of nitrogen fall into the standard D-to-Z colour scale; stones saturated enough to escape that scale earn the "fancy" designation. At the very top of GIA's intensity scale sits Fancy Vivid — the most saturated yellow a diamond can be graded.
That grade is what carries the price. Fancy yellow diamonds are more common than fancy blues, pinks or reds, but a large stone at the vivid end of the scale is another matter entirely — and the auction record tells the story. In May 2014, the 100.09-carat Graff Vivid Yellow sold for $16.3 million at Sotheby's Geneva, setting the world auction record for a yellow diamond — after the surreal episode of being pulled from the block mid-sale and re-offered fifteen minutes later. The previous record holder, the 110-carat Sun-Drop, had made $12.3 million in Geneva in November 2011.
And the most famous yellow diamond of all has never been for sale: the Tiffany Yellow Diamond, cut from a 287-carat rough unearthed at South Africa's Kimberley mine in 1878. Charles Lewis Tiffany bought the rough for $18,000 the following year, and his chief gemologist George Frederick Kunz cut it into the 128.54-carat cushion brilliant the world knows today — worn publicly only twice, by Audrey Hepburn and Lady Gaga. Against that lineage, a 75.54-carat Fancy Vivid Yellow centre stone reads exactly as intended: a once-in-a-generation gem, placed where 4,410 other diamonds can only support it.
A thirty-year tradition, broken wide open
The Fantasy Bra began in 1996, when Claudia Schiffer wore the $1 million original in Victoria's Secret catalogues and on a New York billboard — and it became one of the brand's most coveted honours, passed between supermodels as the designs grew more elaborate. The previous record, the $15 million bra worn by Gisele Bündchen in 2000, stood for 26 years. The last Fantasy Bra before this one was worn by Elsa Hosk in 2018; then the tradition went quiet for eight years.
Its return says something about the moment. Victoria's Secret brought in Jacob & Co. as an official partner of the 2026 show, and the result treats the Fantasy Bra less like a marketing stunt and more like a museum commission — a piece of high jewellery that happens to headline a fashion show. Whether the next one takes another 26 years or another eight, the bar has moved: $50 million, 1,373 carats, zero fabric.
Stories like this are why we love coloured stones at Lumière Gems. Behind every remarkable gem is the same chain of wonders — geology, rarity, craft, and the occasional stroke of human audacity — and the best stones carry all four. The Fantasy Bra just happens to carry 4,410 of them at once.
