From Pangaia’s reef-restoring capsule to Repetto x Birkenstock’s resoleable flats, four new fashion collaborations go big on sustainability credentials.


A good collaboration is one of the few things left in fashion that can make you stop what you’re doing and open a new tab, and this summer has delivered four of them, each with sustainability credentials as real as the buzz. Pangaia is funding a coral reef with a hoodie. Swedish Stockings turned a pile of recycled tights into a dress. Lefrik handed its recycled bags to an artist. Repetto and Birkenstock made a ballet flat you can resole for years. Here’s what to shop, and where.

Sweatshirt front and back.

Pangaia x Coral Gardeners

Pangaia and Coral Gardeners are back for a second capsule, and the sequel keeps the model that made the first one worth owning. Two core silhouettes carry the collection, a 320 GSM hoodie and a 170 GSM T-shirt, both cut in organic cotton and finished with the brand’s PPRMINT peppermint-oil treatment that keeps garments fresher between washes and stretches the time you can wear them before laundering. The donation is the point as much as the cotton: every sale funds Coral Gardeners, the French Polynesia organization that raises heat-resilient coral fragments in underwater nurseries for a year or more before replanting them on damaged reefs.

Stockings dress.

Swedish Stockings x Sylvi Sundkler

Swedish Stockings has spent years arguing that hosiery deserves an afterlife, and its collaboration with artist Sylvi Sundkler is the argument made wearable. The three-piece run, a top, a corset and a dress, is built entirely from nylon stockings collected through the brand’s Recycling Club, the tights most people bin at the first snag. Each piece is made by hand and to order, which keeps production tethered to real demand rather than a warehouse forecast, and it is circularity you can actually see in the finished garment.

Bag.

Lefrik x Coco Dávez

Lefrik handed its recycled-material construction to artist Coco Dávez, and the result is a five-bag collection in vivid green and pink that leads with color and lets the sustainability sit underneath. The bag earns its way into daily use on looks first, and the recycled build is the reason it can stay there without a second thought. The graphic treatment gives a practical everyday piece a reason to be noticed.

Birkenstock shoes.

Repetto x Birkenstock 1774

The buzziest drop of the week is also the one that makes its sustainable case the slow way, through materials and longevity rather than recycled content. Repetto and Birkenstock’s 1774 line reworked three silhouettes, the Arizona, Scala and Opéra, into ballet-inspired shapes finished with gingham footbed linings and detailing in Iconic Pink, Flame Red, and Profound Black. Birkenstock builds the 1774 range in German workshops from specially sourced materials with, by the brand’s own account, a high content derived from natural resources, and the cork-latex footbed at the center of every pair is a layered, resoleable system designed to be maintained rather than replaced.
