5 Sustainable Denim Brands You Need To Know About: Jeans Edition

Flares, Mom or Boyfriend. These brands have got you covered without harming the planet.


As sustainability has become a vital part of the fashion industry, you need to know where you can find jeans that are sustainable and high-quality.

Before we jump into the brands that we love, we need to talk about how you find out if a brand is actually sustainable, as there’s still a lot of greenwashing going on! 

Some key sustainability certifications to look out for include: GOTS (Global Organic Textile Standard) who verifies the organic status of 70% of textiles, often on clothes that are made from hemp, wool, linen or organic cotton. 

Another is Oeko-Tex, which is one of the best-known ethical fashion certifications. This certification tells you the textiles you’re wearing doesn’t contain toxic chemicals. This is done in four tiers, illegal chemicals, legal chemicals, safe and generally safe chemicals. The Oeko-Tex is often found with GOTS. 

The last we’d like to mention is PETA (People for the Ethical Treatment of Animals). This certification is committed to the rights of animals worldwide, ensuring stores and brands are selling 100% vegan products. If you’d like to learn more about other ethical fashion certifications, Fashion Revolution is a great place to start. 

Onto the brands, we have curated a mix of 5 highstreet and high-end brands that offer you amazing quality jeans whilst caring for the planet and people.
