Ganni and Lululemon launched a 22-piece collection on October 15, priced from $70 to $280, that takes its cues from 1980s dance films, according to The Hollywood Reporter.

The collaboration merges Lululemon's technical precision with Ganni's playful Scandi sensibility: leopard prints, ruffled trims and bold color pairings appear alongside leg warmers, boleros and headbands, and Lululemon's popular Define Jacket gets what the outlet calls a distinctly Ganni makeover.

Underneath the fashion-forward details, the collection keeps Lululemon's performance credentials through its proprietary Nulu and Softstreme fabrics. The full range is available at lululemon.com, ganni.com and select stores internationally.

The demand caught even shopping editors off guard. According to Page Six, most styles sold out on the Lululemon website less than an hour after the launch, though the outlet reported that Ganni still had some of the best picks in stock at the time of writing.

The Hollywood Reporter's shopping desk flagged pieces selling quickly, including the Brushed Softstreme Slouchy Pullover at $220 and the Barrel-Leg Pant at $200.

Marie Claire's writer noted that the cropped cardigan sold out minutes after the collection launched, which stung because she considered it an essential for any dancer's studio bag.

No '80s dance-inspired fashion story would be complete without a Hollywood connection, and the brands enlisted Flashdance star Jennifer Beals to front the 'Joy Is a Power Move' campaign alongside singer and dancer Mette, The Hollywood Reporter reports.

The accompanying short film, set inside a dance studio, draws on the era's cinematic language while emphasizing movement as a form of self-expression.

According to Marie Claire, Beals called it an honor to be part of a campaign promoting joy through movement, saying she is a longtime customer of both brands, while Mette described sharing a dance with Beals to her own music as a piece of her dream coming to life.

Ganni creative director Ditte Reffstrup, whose childhood fascination with dance films informed the designs, said she has always been drawn to the energy, determination and sense of freedom in those films, and brought that '80s dance energy into the colors and details mixed with Ganni signatures like leopard and frills, Marie Claire reports.

Lululemon global creative director Jonathan Cheung told the magazine that Ditte said her movement practice was dance and everything flowed from there, praising the use of Lululemon's technical materials combined with Ganni's iconic style.

Marie Claire's writer also tried the collection herself, noting the sheer tracksuit proved the see-through trend is a showstopper, and that the leopard Define Jacket pairs best with neutral workout gear.

The partnership is, as The Hollywood Reporter puts it, a telling example of how fashion and performance brands are finding common ground.

For Lululemon, the collaboration introduces a more expressive design vocabulary to its established silhouettes; for Ganni, it opens another avenue into the growing intersection of fashion, wellness and everyday dressing.

It follows Ganni's earlier collaborations with brands like New Balance, Barbour and Levi's, according to Marie Claire, and lands in a market where the gym has become another place for designer labels to flex their creative muscles.

A sellout this fast signals that shoppers reward collabs that blend performance fabric with statement styling rather than treating activewear as basic gear.

With the Lululemon site reportedly cleared out within the hour, latecomers have limited options.

Page Six pointed readers to Ganni's own site, where it said several of the best picks were still in stock, including the Ruffle-Trim Define Jacket at $180, the Ruffle-Trim MR Tight at $170 in leopard and a brown-and-pink colorway, the $240 retro windbreaker, the $110 ruffle-trimmed cropped tank, the $140 jacquard mesh bodysuit, the $220 slouchy pullover, a $50 five-pack of ruffled skinny headbands, the $200 barrel-leg pants and the $160 Flat Mate ruffle-trim slipper-flats.
