10 Ethical and Sustainable Underwear Brands for Organic Lingerie (2023 Edition)

For most of my life i’ve worn garbage underwear that i got from Target, Costco or Sams Club…

I didn’t know it was garbage obviously, but there are a ton of problems that come with cotton (for example) treated with chemicals like Benzidine.

And wouldn’t you know it

– this chemical probably shouldn’t be anywhere near the cradle of life in between your legs…

Benzidine’s side effects include “major skin irritation, bladder cancer and respiration problems.

So yeah… when i found this out back in 2013 or so, i was actually afraid. I’d gone 20 years just wearing something that could end my chances of having children.

And even worse, back in 2013, there weren’t very many brands creating sustainable underwear.

Thankfully, there are tons in 2023, and i’m here to guide you to some of the most reputable in the industry.

In a 2021 survey, Global Organic Textile Standard found that 75% of respondents preferred sustainable underwear, but only 20% knew where to find reliable brands. A clear need for more accessible, trustable sustainable underwear brands has emerged.

Sustainable underwear isn’t just about comfort and aesthetics; it also aligns with our ethical and environmental values. We need underwear that marries comfort, style, and sustainability, becoming our new normal in 2023 and beyond.

Each year, more brands commit to sustainability, adopting Earth-friendly production methods, pushing beyond fast fashion, and playing a role in the future of slow fashion.

Choosing sustainable underwear also impacts our health. Organic underwear, devoid of harmful chemicals, is skin-friendly and reduces allergies and sensitivities. A report from the Environmental Protection Agency showed about 10% of the global population suffers from contact dermatitis, which can be worsened by non-organic clothing.

We’ve picked out the top 11 sustainable and ethical underwear brands that effortlessly blend style, comfort, and responsibility. Ready to feel incredible about your wardrobe, well-being, and our planet?

Start with your underwear.

Wondering how to identify genuinely sustainable underwear brands?

Look out for the use of natural or recycled materials, transparent manufacturing processes, and labels like Fair Trade, GOTS, or BlueSign, signaling sustainability and ethical commitment.

A quick guide to the Global Organic Standard Textile criteria:

ORGANIC FIBERS: Look for GOTS labels indicating at least 70-95% certified organic fibers, grown without synthetic pesticides, herbicides, or GMOs.

ECOLOGICAL AND SOCIAL STANDARDS: GOTS certification covers environment and social norms, from chemical inputs to wastewater treatment and ethical worker treatment.

COMPREHENSIVE COVERAGE: GOTS covers all stages from processing to distribution of textiles made from at least 70% organic fibers.

THIRD-PARTY CERTIFICATIONS: Fiber production certification is covered by international standards approved in the IFOAM Family of Standards.

GOTS CERTIFICATION REQUIREMENTS: Look for annual inspections, product tracing, input assessments, wastewater treatment verification, social criteria monitoring, and risk assessment-based quality policy.

To verify GOTS certification, check for a visible label showing the GOTS logo, label grade, certification body details, and license number or certified entity name. Alternatively, check the certified suppliers database or their GOTS Scope Certificates, issued by a GOTS Approved Certifier.

With this information at hand, let’s dive into the top 11 sustainable underwear brands.

An incredible differentiator i’ve seen with Boody (Organic Bamboo products!) is their Period and Leak-proof Classic bikini’s that cover you from Light to Heavy.

That kind of inclusivity, affordability and thoughtfulness is exactly why they’re on this list.

Bamboo is silky soft, thermoregulating, moisture wicking, UPF50+ sun protection, and anti-static, getting softer and softer with each wash. 🎋

With great pricing to bag, the only negative we really see is the fact that they don’t have any sizes under XS or larger than XL.

What Exactly is Ethical and Sustainable Underwear?

Like we spoke about before, ethical and sustainable underwear should fit our ethos of people, planet and passion.

Meaning that these people creating brands like the list above, care about the planet, and have a passion for preservation, even if that means less profit, and scale.

We couldn’t be any happier with the myriad of conscious brands coming gaining popularity right now.

Down with fast fashion, terrible working conditions, racism, and corporate greed.

Up with considerate people, a clean planet, and passionate artists.

How Can Sustainable Underwear Benefit You?

  • Healthier for your skin, immune system, and free of free radicals and micro-plastics.
  • Better for the air you breathe – with less waste and carbon emissions from tradiotional practices.
  • Longer lasting and higher quality materials – thanks to optimized manufacturing practices that you will benefit from in the long run.
  • Your money goes further with sustainable practices, and encourages corporations to follow suite.

To Wrap it Up.

Picking the right underwear is easy when you follow your ethics and moral compass.

Especially when you have a list like ours to help you make the right move. (:

We plan on covering every kind of wearable item from sustainable brands around the globe, so make sure to follow us on our journey!


  1. What is the best sustainable fabric for underwear?

    People will say TENCEL™ which is made from cellulose, Organic Cotton, Hemp, and Bamboo for it’s anti-fungal properties
  2. What is Sustainable Underwear?

    Sustainable underwear is quality underwear created from eco-friendly fabrics made by people who are paid a fair wage. You want the underwear to last through many washes and be comfortable for you.
  3. What is the best natural fiber for underwear?

    People will go back and forth with this but again, it depends on what you describe as best. For us, best entails price, conditions, comfort, fit and form. Organic Cotton, Hemp, TENCEL and Bamboo would fall into those categories.
  4. Is Organic Cotton better for you?

    Again this depends on what you consider better for you. Of course organic cotton is better than non-organic cotton, which is treated full of chemicals and pesticides, not to mention terrible working conditions for the producers and manufacturers.
