The Best OEKO-TEX® Clothing Brands that are also Sustainable (2025)
As sustainable fashion grows in popularity, many brands strive to appear eco-friendly and ethical to consumers.
However, the majority of them have barely taken any steps in the right direction. They use greenwashing as a key marketing tool, making it harder to determine a product's sustainability.
Thankfully, some third-party certifications are making shopping responsibly easier than ever. When a piece of clothing is certified by one of these, we know that it is a better choice for us and the planet.
One example is the OEKO-TEX® label, which you have probably come across at some point when shopping for clothes. Many sustainable brands are selling clothing with this label, and we have selected 15 of them in this article!

What does the OEKO-TEX® label mean and why is it important?
The OEKO-TEX® label consists of various third-party certifications that ensure a product, typically a textile, is free from harmful substances.
The most commonly found label is the Standard 100 by OEKO-TEX®. This label indicates that a product's components - such as materials, threads, trims, zippers, linings, buttons, dyes, and coatings - have undergone rigorous testing for toxic chemicals and are safe for use.
The MADE IN GREEN by OEKO-TEX® label goes further by certifying that the product comes from an ethical and sustainable production process at every stage.
All the OEKO-TEX® labels are trustworthy certifications since OEKO-TEX® is a third-party body, and it verifies products according to a given set of standards. So when a product has one of these labels, we know that it is a healthier version for us and the environment.
When shopping for clothes or any other textiles, always check the label. Since we wear these items close to our skin, we want to avoid absorbing any harmful substances into our bodies.
