Taylor Swift’s Kansas City Chiefs Ganni dress hints at fashion’s next material era as biotech and textile recycling innovations race to replace unsustainable materials.
Taylor Swift made her first appearance for the Kansas City Chiefs’ 2025-2026 season in a black, jersey-style Ganni minidress — customized with “Chiefs” and her signature number 13. But that wasn’t the only defining feature; the dress was crafted with Cycora, a regenerated polyester developed by Los Angeles–based material science company Ambercycle.
Ambercycle’s Cycora is one of the most advanced examples of textile-to-textile regeneration. Rather than relying on recycled bottles, its system captures post-consumer clothing, breaks it down on a molecular level, and reforms it into virgin-quality polyester. This closed-loop approach addresses one of the industry’s biggest waste streams — synthetics — which account for more than half of global fiber production and shed microplastics throughout their life cycle.
In 2023, Zara parent Inditex signed a €70 million agreement to integrate Cycora across its production lines, signaling growing confidence in chemical recycling as a scalable solution. Ganni’s collaboration followed shortly after, part of its commitment to phase out virgin polyester entirely within the decade.
Yet polyester’s reinvention is only one part of fashion’s materials revolution. The Ganni dress comes as MycoWorks, a California-based company known for its Fine Mycelium platform, announced that it would shift focus from growing mycelium to refining it — an evolution of strategy that reflects the industry’s current inflection point.
The company’s flagship material, Reishi, is a mycelium-based alternative to leather grown in sheet form rather than assembled from fibers. Its latest Rei-Tan process increases tensile strength up to five times, creating a product that can meet luxury performance standards without plastic fillers or animal hides. “Our Rei-Tan process elevates mycelium to a level that has won the hearts of some of the world’s most discerning designers,” CEO Matt Scullin said in his open letter to partners.
A different type of leather is also entering the picture. Biomedical engineer George Engelmayr, founder of Cultivated Biomaterials, says the company has developed a way to grow real leather from live animal cells without slaughter. “We are the first company in the world to first sell a cultivated leather product,” Engelmayr told CNN.
“This is a leather grown harmlessly from the cells of a cow that is still alive… It is real.” The cow who donated her cells, Angel, continues to live at a sanctuary in New York. Her cells are placed on plant-like scaffolding and grow into a sheet of skin. “When the cells attach to these fabrics, they’ll begin to form collagen and other proteins that are consistent with conventional leather,” Engelmayr explained. Instead of chemical tanning, he uses tree bark to finish the hides, making the process nearly pollution-free. The method could significantly reduce waste and emissions if scaled.
This expansion of biofabrication — whether through mycelium, cultivated cells, or plant-based substrates — signals a reshaping of fashion’s material DNA. Companies like Polybion in Mexico, Modern Meadow in New Jersey, and Ecovative in New York are investing in similar innovations that bridge biotechnology and design. Each aims to deliver materials that match the look, feel, and longevity of traditional fabrics while lowering ecological impact.
Swift’s Ganni minidress, while playful in form, symbolized a much more serious opportunity, where biomaterials, once confined to R&D labs, are now shaping the textures and ethics of what we wear next.
