Sustainable Materials in Luxury Fashion: What to Look For
Luxury fashion is evolving—and sustainability is now at the forefront of the industry. As designers and consumers become increasingly conscious of their environmental impact, the use of eco-friendly materials has grown significantly. From innovative textiles like recycled polyester to natural choices like organically grown cotton, these materials blend sustainability with sophistication. Let’s take a closer look at some of the most popular sustainable materials we’re seeing on the runways and how to keep them in excellent condition.
Organic Cotton
Organic cotton is a cornerstone of sustainable luxury fashion, prized for its eco-friendly cultivation and superior quality. Unlike conventional cotton, organic cotton is grown without synthetic pesticides or genetically modified seeds, significantly reducing its environmental impact. Instead of using herbicides, organic cotton manufacturers cultivate crops using eco-friendly methods like crop rotation and composting to maintain soil health and minimize water usage.
Designers like Stella McCartney and Eileen Fisher have embraced organic cotton for its versatility and ethical production methods. From tailored shirts and casual T-shirts to elegant dresses and home textiles, organic cotton is a staple in collections that prioritize sustainability without compromising on quality or style. Its breathable, hypoallergenic properties also make it a popular choice for those with sensitive skin, further elevating its appeal in the luxury market.
To care for organic cotton garments, it’s best to wash them with mild, eco-friendly detergents in cold water to preserve the integrity of the fibers and help the garment keep its shape. Air drying is recommended to avoid shrinkage and prolong the fabric’s life as well. For wrinkles, use a low-heat iron or steamer to help maintain the material’s natural softness and structure. Taking a bit of time to wash your organic cotton with care can help prolong the life of the garment, allowing you to wear it season after season instead of repurchasing fast fashion each year.
Recycled Polyester
While polyester is a common culprit in fast fashion pieces, recycled polyester is a game-changing material in sustainable luxury fashion. Recycled polyester offers a high-performance alternative to traditional polyester while significantly reducing environmental impact and removing excess fabric from the waste cycle. Made by transforming post-consumer plastic waste (like bottles) into durable, versatile fibers, recycled polyester helps divert plastic from landfills and oceans. This process requires less energy and water compared to producing virgin polyester, making it a more eco-friendly choice for designers and consumers alike.
Many of today’s top fashion designers have made it a point to use recycled polyester in their garments and accessories. For example, Prada’s Re-Nylon collection is crafted from recycled fibers collected from the ocean, reducing the line’s environmental impact and giving back to the planet. This material’s adaptability makes it ideal for outerwear and activewear as well as accessories, offering the same durability, wrinkle resistance and moisture-wicking properties as conventional polyester.
Caring for recycled polyester involves washing less frequently and using a gentle detergent in cold water to conserve energy and prevent fiber degradation. One of the challenges with polyester, recycled or not, is microplastic shedding during washing. To minimize this, use a washing bag designed to capture and collect microfibers. Our team of fashion experts also recommends air drying to save energy and extend the life of the material.
Hemp
Hemp is one of the most sustainable and versatile materials in luxury fashion, celebrated for its eco-friendly cultivation and natural durability. Unlike conventional crops, hemp grows rapidly with minimal water and without the use of synthetic pesticides or fertilizers. Its deep roots improve soil health by preventing erosion and replenishing nutrients, making it a regenerative crop that supports sustainable agriculture. Hemp also absorbs more carbon dioxide than most plants, contributing to its status as a highly eco-friendly fiber.
Luxury brands like Mara Hoffman and Gabriela Hearst have embraced hemp for its aesthetic appeal and environmental benefits. Hemp fabric has a unique texture that softens with wear, offering a blend of rustic charm and refined elegance. Its breathability and moisture-wicking properties make it ideal for everything from tailored blazers and breezy summer dresses to casual trousers and accessories. Designers often pair hemp with other sustainable fibers like organic cotton to create innovative, high-performance blends that cater to luxury consumers.
Hemp can be a great choice if you’re a lowkey shopper looking for garments that require less care when cleaning. The material is naturally resistant to bacteria and odors, making it an ideal option for anyone who doesn’t have the time to specialty dry their clothing after every wear. Unlike other sustainable luxury materials, hemp can also handle a bit more heat when ironing, making it a bit easier to care for. We recommend washing with mild detergent in cold water to prevent your garments from shrinking. Tumble dry on low heat and iron on the medium setting.
Cork
It’s not just for your bottle of wine anymore—cork is a remarkable, sustainable material making waves in luxury fashion. Prized for its eco-friendly harvesting process and one-of-a-kind aesthetic and pattern, cork is harvested from the cork oak tree without harming the tree. This allows the cork to regenerate, allowing the material to be collected safely once a decade. This process not only preserves the tree but also supports biodiversity, as cork oak forests are vital ecosystems that absorb large amounts of carbon dioxide and provide habitats for various wildlife species.
Cork has become a recurring choice on the runways of Saint Laurent and Dior. Its water-resistant properties make it especially suited for their summer and cruise collections. It’s most commonly used in accessories like handbags, shoes and even watch straps, offering a natural, textured look that appeals to eco-conscious consumers. Additionally, its natural elasticity and hypoallergenic properties make it a practical and comfortable choice for most types of other accessories.
Caring for cork products is simple, as the material is naturally stain-resistant and easy to maintain. To clean cork, wipe it gently with a damp cloth and mild soap, avoiding harsh chemicals that can damage its surface like bleach or countertop cleaners. Keep cork items away from prolonged exposure to direct sunlight and excessive moisture to preserve their natural appearance and durability.
