7 fashion collaborations to know this September, from Supreme x Nike to Sacai x Levi’s

September may be best known as fashion month, with fashion weeks taking over major cities around the world, but the runways are far from the only thing keeping the industry busy. This month has also delivered a strong line-up of collaborations, bringing together streetwear heavyweights, designer labels and outdoor specialists for the season ahead. From Supreme and Sacai to Arc’teryx, here are seven fashion collaborations worth knowing this month

Supreme and Nike are back for Fall 2026, continuing their long-running partnership with something a little different: there is not a sneaker in sight. Instead, the pair turn their attention entirely to clothing, led by a reversible faux-fur parka alongside water-resistant nylon jackets, cargo trousers, football jerseys, fleece sets and matching headwear. The result brings Nike’s sporting DNA into Supreme’s world of skatewear, oversized proportions and relaxed layering without overcomplicating the formula.

Following its recent denim collaboration with Hailey Bieber, Gap heads to Paris for its first partnership with French label A.P.C. Built around a shared love of effortless everyday dressing, the 37-piece collection mixes Gap’s American casualwear with A.P.C.’s understated minimalism across denim, Oxford shirts, knitwear, tailoring and outerwear. Rather than reinventing either brand, it sharpens familiar staples with cleaner proportions, premium fabrics and subtle details, giving classic Americana an unmistakably Parisian sense of ease.

Known for mixing luxury tailoring with references to Chicano culture, Willy Chavarria is probably not the first designer that comes to mind when you think of Ugg – which is exactly what makes the pairing interesting. Drawing on California biker culture, he swaps familiar chestnut suede for black leather, exaggerated proportions and metal hardware across chunky boots, clogs and slippers. A graphic T-shirt and socks round things out, bringing Chavarria’s tougher attitude into Ugg’s famously cosy world.

Supreme also teamed up with high-end Japanese menswear label A.Presse this month, and the result could hardly feel more different from its Nike partnership. Known for meticulously reworking vintage menswear, A.Presse puts fabric and construction first across an 11-piece collection of leather jackets, camouflage M-65 outerwear, cargo trousers, a cotton-silk suit, Oxford shirting, hoodies and accessories. Compared with Supreme’s usual appetite for bold graphics and logos, everything feels noticeably quieter, letting the materials and subtle detailing take centre stage.

Levi’s and sacai return for a third collaboration, once again reshaping classic denim through Chitose Abe’s signature hybrid construction. The 12-piece collection centres on four silhouettes in rigid and washed indigo, including a relaxed Sherpa Jacket wrapped in faux shearling and a sculptural Blouson Jacket with sacai’s signature utility sleeve pocket. Throughout, familiar Levi’s staples are exaggerated and reconstructed through contrasting textures, unexpected proportions and reworked patterns, while still retaining their unmistakable denim DNA.

Marking the eighth chapter of their ongoing partnership, Song for the Mute and Adidas are back with another deliberately imperfect take on sportswear. The Australian label gives the Samba collapsible heels and worn-in suede, leather and nubuck finishes, while the SL 72 Pro mixes archival running cues with modern cushioning. Quarter-zips, blazers, track pants and accessories carry the same approach into clothing, with distressed finishes, vintage treatments and deconstructed details giving the entire collection a convincingly lived-in feel.

After 25 years of working together, Beams and Arc’teryx look back at their shared history with “Koyo,” an anniversary collection inspired by Japanese autumn foliage and the beauty of changing seasons. Arc’teryx’s Blaze and 24K shades meet signature Beams orange across six pieces, including the revived Theta AR Jacket, Gamma Jacket, cargo trousers and Konseal backpack. Coinciding with Beams’ 50th anniversary, it turns the pair’s familiar colour-blocking language and shared archive into a fitting celebration of both milestones.
