40 Sustainable Clothing Brands for Every Type of Closet

The fashion industry is responsible for an estimated 10% of total carbon emissions and, with all of the news about fast fashion’s continued contributions to climate change, you might be looking your own closet and thinking about making some changes to the way you fill it. 

From established players like Patagonia and Eileen Fisher to upstarts like R Collective and Charle Swim, ethical fashion brands are re-assessing the fabrics, factories, and packaging that have long been held as industry standard to build product lines that are better for the earth and are great for your closest. In the world of sustainable clothing, bikinis can be made from fishing nets and dresses can come from banana peels. And slow fashion now comprises every style. Looking for some ethereal 70s eco-fashion? Christy Dawn has you covered. What about Gen Z-approved streetwear? Look no further than Pangaia. 

With all the new and exciting progress being made in the space — from manufacturing to design — below is a list of some of our favorite sustainable clothing brands that can satisfy all of your eco-friendly fashion needs.

Even the dreamiest flea market finds tend to need an alternation or two, which is the thinking behind sustainable denim brand, RE/DONE. They first launched in 2014 with 300 tailored vintage Levi’s and immediately racked up a waiting list of thousands of people. The brand now offers upcycled luxury (and we mean luxury — think: one-of-a-kind patched jeans from the ‘70s), a reduced water denim line, and a marketplace where customers can buy and sell pre-loved goods from the brand and beyond.

Our Criteria

A list is just a bunch of words unless there is research to back it up. So here’s the thinking behind ours…

One of our first considerations when choosing who we featured on this list was the materials used to make the clothes. Something many sustainable brands look to avoid is the use of “virgin” materials— previously unused raw material that has not been a part of any processing other than in its own production. All of the brands on this list use environmentally preferred materials in their clothing. This could be recycled fabric bases like polyester and nylon, or deadstock materials that would otherwise end up in a landfill. The materials may also be plant-based, like textiles made from wood pulp or banana stems. 

Next, we looked into how the clothing is manufactured, the amount of water and energy used, and if any hazardous chemicals are a byproduct of the production process. We also looked at who is making the clothing, most notably if they are 18 years or older, and if they are getting paid fair and liveable wages. 

Finally, we looked at the last step in the supply chain: shipping. Nearly all of the above companies use recyclable, compostable, or biodegradable materials in their packaging materials. And a large percentage of them go the extra mile by offsetting the carbon produced by the travel that’s involved in shipping their products to you.

All of the above brands’ production processes — from materials to transportation —  include some sizeable variation of these factors, making their clothing cleaner for the world and for you. And that’s something to celebrate. Or, at the very least, something to be featured on a list of sustainable clothing brands.

Note: The list under each brands’ “Eco-Friendly Practices” is not meant to be exhaustive. All of the above companies have made their sustainability efforts and processes available to consumers on their websites.
