Miu Miu’s Paris Show Proves Sportswear Style Is Luxury Fashion’s Next Billion-Euro Bet

Miuccia Prada spent the weekend convincing Paris that gym knickers and track pants belong on a runway alongside tailored blazers, and the result was one of the clearest statements yet that sportswear style has become the defining language of modern luxury fashion.

At Sunday’s Miu Miu show during Paris fashion week, the designer sent out a collection built on what she described backstage as “real clothes” — the unglamorous staples people actually reach for when running errands, rather than the exaggerated gowns of traditional haute couture. Her goal, she said, was to take that everyday reality and make it “more interesting, more rich” by colliding it with tailoring and polish. The show opened with crisp, pleated checked skirts worn with equally crisp blazers, but the sensible footwear was swapped for brightly coloured trainers. A few looks later, spiky heels returned, crop tops slid beneath blazers, and track pants — the kind usually reserved for lounging at home — appeared under sharp knitwear and structured jackets.

How sportswear style took over the Miu Miu runway

The through-line of the collection was deliberate friction: gym-class basics dressed up, formalwear stripped down. Sports bras were reworked as sequinned party tops, some worn alone and others layered over clingy jersey. Gym knickers got the same elevated treatment as the skirts and blazers around them. Even denim got a twist — a collaboration with Wrangler reimagined vintage jeans with low-slung hips and shoelace-style fastenings in place of buttons or belts. Prada called the overall approach “nonconformist dialogues exploring a form of friction and tension,” a tidy summary of a trend that has quietly been building across the industry: the deliberate clash of performance wear and polished tailoring, designed to look both effortless and expensive.

It’s not a new idea for Miu Miu, a brand built almost entirely on the pleasure of subverting the ordinary. Since launching in 1993 as a younger, cheekier sibling to Prada, the label has turned plasters, aprons and embellished trousers into objects of desire. But this season’s full embrace of sportswear style feels like a natural extension of that instinct, pushing gym-floor basics into spaces usually reserved for eveningwear and formal tailoring.

A billion-euro bet on “real clothes”

The timing is notable. Luxury fashion has been grappling with a slowdown in big-ticket spending, yet Miu Miu has continued to outperform much of the market. The brand currently ranks second on the Lyst index, the quarterly ranking that tracks consumer demand for fashion labels, trailing only Chanel. Sales climbed 3% to more than €700m in July alone, making Miu Miu one of the few bright spots in an otherwise cautious luxury sector.

Much of that resilience comes down to a sharply defined customer the brand calls the “Miu Miu girl” — someone drawn to clothing that reads as a little odd, a little undone, and unexpectedly sexy. Crucially, that archetype isn’t tied to a single age bracket or gender, which helps explain the eclectic casting on Sunday’s runway. Emma Corrin paired white knickers with a cropped croc jacket, Olivia Colman walked in a cracked suede skirt suit, and Jamie Bell wore low-rise, Prince of Wales check trousers with a two-tone vest. The mix of generations and genders reinforced the idea that this version of sportswear style isn’t aimed at a narrow slice of shoppers chasing trends, but at anyone willing to mess with the usual rules of dressing up or down.

Beyond the catwalk: sport as cultural strategy

Miu Miu’s interest in sportswear style extends well past the runway. Earlier this year the brand partnered with New Balance on a performance-wear collection for tennis star Coco Gauff, who debuted the pieces at the Italian Open in May before wearing them again on Centre Court at Wimbledon. It’s a calculated move: by dressing an athlete competing at the sport’s biggest stages, Miu Miu gets visibility far beyond the fashion crowd, while reinforcing the same blend of sport and sophistication that defined Sunday’s show.

That strategy fits a broader pattern at the brand, which has spent the past 15 years building cultural credibility through projects that have little to do with clothes at all — a literary club that has tackled Simone de Beauvoir and Ama Ata Aidoo, and a series of female-directed short films from names including Mona Fastvold and Miranda July. The common thread is an insistence that Miu Miu isn’t just selling garments but a whole sensibility, one where sportswear style, intellectual curiosity and a slightly subversive sense of humour all sit comfortably together.

Whether rivals follow Miu Miu’s lead into sports bras and trainers on the runway remains to be seen, but the commercial numbers suggest there’s little incentive to abandon the formula. In an industry anxious about where the next wave of luxury spending will come from, a brand that can turn a tracksuit into “more interesting, more rich” fashion — and back it up with sales growth — is hard to ignore.
