The fashion industry is undergoing an unprecedented structural transformation, driven by the convergence of European regulation, consumer pressure, and technological innovation. As of January 1, 2026, the European ecodesign regulation for textile products will require all clothing sold in the European Union to have a "digital passport" containing the origin of raw materials, manufacturing conditions, carbon footprint, and recycling instructions. This text, negotiated over four years, marks the end of the opacity that characterized fast fashion supply chains. (
French luxury houses have taken the lead. LVMH launched its Aura Blockchain Consortium platform in 2024 – developed with Microsoft and ConsenSys – which now certifies the authenticity and traceability of 85% of its products. Each Louis Vuitton bag, Dior bottle, and pair of Berluti shoes is linked to a digital twin accessible via a QR code. Kering (Gucci, Saint Laurent, Balenciaga) has adopted a similar system based on the Polygon blockchain, while Hermès uses its own proprietary solution for its silk scarves and Birkin bags, with each skin traced back to the farm of origin.

Fast fashion, identified as one of the most polluting industries on the planet – responsible for 10% of global CO₂ emissions and 20% of freshwater pollution according to the UN – is facing a regulatory tsunami. France has banned advertising for textile products whose selling price is less than 50% of the estimated production cost, a measure directly targeting Shein and Temu. The National Assembly is examining a proposed environmental tax of 5 euros per item on imported clothing that does not meet European ecodesign standards. Meanwhile, the platform Shein, valued at 66 billion dollars, saw its European sales decline by 12% in the fourth quarter of 2025. (
The second-hand market is booming and restructuring the entire industry. Vestiaire Collective, the French unicorn for premium pre-owned fashion, has surpassed 25 million members and achieved a turnover of 450 million euros in 2025. Vinted, the Lithuanian giant, claims 100 million users in Europe. Luxury brands themselves are entering the market: Gucci has launched Gucci Preloved, Balenciaga offers Balenciaga Re-Sell, and Chanel is exploring a certified take-back pilot program. According to the Boston Consulting Group, the global second-hand fashion market will reach $350 billion by 2028, representing 20% of the total apparel market. (
Beyond traceability and recycling, innovative materials are redefining what it means to "clothe oneself." Stella McCartney uses mushroom leather (Mylo), Adidas is marketing sneakers made from synthetic spider silk (produced by the Japanese startup Spiber), and the French house Coperni presented a dress at Paris Fashion Week made entirely from captured CO₂ fibers. These innovations, still marginal in volume, signal a paradigm shift: the fashion of the future will no longer be extractive but regenerative. As François-Henri Pinault, CEO of Kering, summarizes: "Luxury has always been synonymous with rarity and excellence. Sustainability is not a constraint—it is the very definition of luxury in the 21st century." (
