45 Sustainable Clothing Brands: The Ethical Masterlist
In the world of fashion, there is no more serious faux-pas than the trend of fast fashion.
To be blunt, it’s unsustainable and unethical.
And let’s be honest: do mass-produced clothes even look that good?
That’s why we’re exploring brands that are out to change the status quo.
We want to not only avoid fast fashion but eliminate it altogether by supporting ethical and sustainable clothing brands that are creating a fairer and healthier world.
We’ve created many slow fashion brand guides over the years, but this is the big one. It’s basically an encyclopedia of all things ethical and wearable!
This has involved a lot of trying on, reading tags, and scouring impact reports. We’ve done all the dressy digging and style sniffing for you (a process you can learn about at the bottom).
Ready to feel inspired, invigorated, and like you can dress to save the Earth?
In the case, here are the best sustainable clothing brands.

HOW WE CHOSE THE BEST ECO FRIENDLY CLOTHING BRANDS
Fashion is mind-bogglingly massive.
It’s also one of the dirtiest (second only to coal).
Fortunately, many sustainable fashion brands are stepping into the spotlight.
Still, there’s a lot of fast fashion brands and greenwashing to sift through as we peruse the world of “sustainable” fashion.
To help us along the way, we have our trusty sustainable and ethical fashion criteria to ensure we shop sustainability:
It’s important to consider materials first and foremost, as this is where the majority of a garment’s impact comes from.
Oftentimes, at least a little synthetic material is blended in (typically spandex/elastane) or used to make an entire garment in the case of recycled plastics and leftover fabrics or deadstock materials.
For when synthetics can’t be avoided, don’t forget to use a Guppy Friend Bag to prevent microplastics from entering our waterways.
Don’t forget the non-toxic and AZO-free dyes for the brightest colors and greenest planet.
- Certifications: Forestry Stewardship Council (FSC), Greenguard Gold, OEKO-TEX 100, Global Organic Textile Standard (GOTS), Global Organic Latex Standard (GOLS), MADE SAFE, Global Recycled Standard (GRS), bluesign®
Supply chain & fair labor practices:
In addition to sourcing the most sustainable fabrics, we also want these ethical brands to treat their workers well, from sourcing to sewing.
We look for transparency that demonstrates all workers in the supply chain have been provided with living wages and safe working conditions. We don’t tolerate child labor or slave labor and are happy to see these brands don’t either.
Green business practices:
This is a catch-all for any other initiatives to support our planet.
These commonly include garment recycling programs, minimized or reused textile waste, carbon footprint offsets, the use of renewable energy, sustainable practices in the office, closed-loop or manual ethical manufacturing techniques, and low or zero waste packaging.
Fashion isn’t traditionally the most body-positive place.
Instead of body shaming of impossible-to-fit ideals, we look for inclusive sizing and real models (instead of airbrushed Barbie Dolls). Instead of gendered clothes, we look for brand’s ethics that cater to all cultures, races, ethnicities, gender identities, and sexual orientations.
Bonus points for brands that are owned and operated by women or BIPOC individuals.
Community & charitable giving:
With the resources to do it, some sustainable brands are doing even better by donating money or clothes, volunteering, organizing charitable events, using their platform for good, or being a member of 1% for the Planet.
FINAL THOUGHTS ON ECO FRIENDLY CLOTHING BRANDS
We’d like to take a quick moment to reflect on how many sustainable fashion brands there are that are changing the garment game.
If you found this list as helpful as we hope, share it with your friends and help us spread the good word on green garments.
It’s great that brands like these exist, but that only means so much if we don’t support their efforts to revolutionize the entire fashion scene.
