Quick links

What makes a fashion brand sustainable?

A sustainable fashion brand will use eco-friendly fabrics and often showcase its third-party certifications, including GOTS certifications for organic materials, GRS certifications for recycled fabrics, and OEKO-TEX and/or Bluesign certifications for dyes and fabric finishes.

These certifications attest that no toxic chemicals have been used during the treating of the fabrics, a key point when looking for brands that don’t put their workers’ health and the environment at risk for the sake of stylish pieces!

The mainstream fashion industry is also infamous for unfair labour standards, so you can expect sustainable brands to also be transparent about working conditions under their supply chain.

Conscious companies will often have their factories audited by third parties like the Ethical Trading Initiative (ETI) and SEDEX, or be part of Fairtrade or other ethical trade organizations such as Fair Wear or WRAP.

Our guides to child free labour brands and brands that pay a living wage will help you find more great ethical brands.
