15 Best Eco-Friendly Clothing Brands With Nontoxic Fabrics & Practices

When we think of pollution, we think of big oil companies and smog from coal mines—but the truth is, fast fashion is one of the central polluting industries in the world. Not only is excessive clothing production harmful to our planet, but garment production harms farmers and producers due to chemicals and waste.

Thankfully, there are many eco-friendly clothing brands utilizing sustainable production methods. These brands use low-impact dyes, upcycled natural materials, and organic cotton to create the very best sustainable and organic apparel.

It can feel overwhelming to try to break a fast fashion habit, but making the switch to eco-friendly clothing doesn’t have to happen over night. Start small, keeping these environmentally friendly clothing brands in mind for the next time you get the itch to update your closet.

For even more eco-friendly fashion brands, check out our guides for sustainable shoes, ethical handbags, and organic cotton basics.
