Our ratings are based on a scale from 1 (We avoid) to 5 (Great) How we rate


Our “Planet” rating evaluates brands based on the environmental policies in their supply chains, from carbon emissions and wastewater to business models and product circularity. Here we rate Kings of Indigo “Great”. These are a few factors influencing its score:

  • It uses a high proportion of lower-impact materials including organic cotton, and it publishes an aggregate breakdown of materials used.
  • It uses lower-impact materials that help limit the chemicals, water, and wastewater in its supply chain.
  • The brand prioritises recyclable textiles by minimising its use of fibre blends.
  • It uses some recycled packaging. 
  • It captures rainwater to reduce water use in its supply chain.

Workers’ rights are central to our “People” rating, which assess brands’ policies and practices on everything from child labour to living wages and gender equality. Here we rate Kings of Indigo “Good”. These are a few factors influencing its score:

  • Most of its final stage is located in low risk countries or certified facilities, however it does not publish an aggregate breakdown of suppliers.
  • It traces most of its supply chain.
  • Its Code of Conduct covers ILO Four Fundamental Freedoms principles.
  • It audits some of its supply chain including all of the final production stage.
  • It claims to have a program to improve wages but there’s no evidence it ensures its workers are paid living wages in most of its supply chain.

Brands’ animal welfare policies and, where applicable, how well they trace their animal-derived products are the focus of our “Animals” rating. Here we rate Kings of Indigo “Good”. These are a few factors influencing its score:

  • All of its animal-derived products consist of recycled or certified alternatives including recycled wool.
  • It doesn’t appear to use fur, angora, leather, shearling, cashmere, alpaca, mohair, or down.

Based on all publicly available information we’ve reviewed, we rate Kings of Indigo “Great” overall.
