The term “sustainable fashion” is frequently used, but it is not a uniform product standard. On this page, we explain which specific details for textiles are comparable and verifiable: material composition, country of production, certifications, and their scope. You can find the information that applies to an item directly on the product.

Was ist nachhaltige Mode?

"Sustainable fashion" is not a legally defined product standard. The term can refer to various environmental or social aspects and does not in itself state which specific criteria a garment meets. Therefore, specific product information is more meaningful: material and fiber content, country of production, as well as existing certifications and their scope.

Materials and standards: What they specifically mean

Materials and standards: What they specifically mean

Material designations and certifications answer different questions about what they specifically state. Organic cotton describes how the cotton is grown; information about recycled fibers describes the material content. GOTS is a textile standard for certified organic fibers and their processing and also includes human rights and social criteria. Fairtrade Cotton refers to cotton within the Fairtrade system. OEKO-TEX STANDARD 100 identifies textiles tested for harmful substances. The Global Recycled Standard (GRS) verifies recycled materials and their supply chain and includes additional processing requirements. Which information applies to a specific product is stated on the respective item. No material is "sustainable" by default based solely on its fiber designation.

<strong>Buying sustainable clothing online:</strong> what you should look out for

Buying sustainable clothing online: what you should look out for

Finding sustainably produced clothing online is easier today than it used to be. At the same time, not every green claim is substantiated. Therefore, keep a few points in mind when shopping online: Is the exact material composition listed? Is an independent seal mentioned for this specific product, rather than just for the brand? Do you know in which country the item was manufactured? And is the quality such that you can wear it for a long time? By the way, since September 27, 2026, general terms like "environmentally friendly" may only be used in advertising in Germany under strict conditions. Specific details are therefore a good sign.

Brands in our range and their standards

Materials, Seals & Standards at a Glance

What seals and standards specifically mean

Certificates can provide specific information when the certification system, product scope, and area of application are clear. For certified textiles, GOTS includes requirements for organic fibers, processing, as well as human rights and social criteria. Fairtrade Cotton refers to cotton produced and traded according to Fairtrade rules. OEKO-TEX STANDARD 100 is a testing and certification system for textiles tested for harmful substances. The GRS verifies recycled materials, their traceability, and additional processing requirements. The deciding factor is always which standard applies specifically to the individual item in question.

Sustainable fashion in everyday life: less, longer, more conscious

You often make the biggest difference not at the point of purchase, but afterwards. Clothing that is worn for a long time replaces new clothing. That is why it is worth buying consciously less but of higher quality, paying attention to fit and workmanship, and taking proper care of your clothes: wash less often and at lower temperatures, air dry, and repair minor damage. Anything you no longer wear can be given a second life through second-hand or clothing swaps.
