We’ve researched and personally tested dozens of sustainable underwear and lingerie brands — these are our top picks made from natural and organic materials by ethical brands.
Few things are as personal as what we’re wearing under our everyday wardrobe. Our underwear starts our day with us; it should be comfortable, make us feel confident and effortlessly sexy, and — ideally — reflect our values for ethics and sustainability.
There are a growing number of ethical and sustainable clothing brands that respect both people and the planet. But ethical lingerie and sustainable underwear brands — especially ones that make us look and feel fantastic — are fewer and farther between.
Why consider sustainable underwear and lingerie?
Opting for sustainable underwear and lingerie is a great choice for both your health and the environment. Rather than making intimates with conventional materials which often have unwanted chemicals and pesticides, sustainable brands prioritize natural and recycled materials that are made with less harmful chemicals and dyes. Lingerie and underwear made with sustainable fabrics like organic cotton, hemp, and bamboo are gentler for our skin and nether regions as they are naturally hypoallergenic, breathable, and reduce the risk of any allergic reactions.
Underwear and lingerie made with natural and skin safe materials also helps reduce exposure to PFAS, harmful “forever chemicals” often found in synthetic fabrics and treated textiles. PFAS can accumulate in the body, potentially leading to health risks like hormone disruption and immune system effects. Sustainable brands prioritize nontoxic, natural, and certified safe materials, minimizing the risk of PFAS exposure while also protecting the environment from chemical pollution.
To help further avoid PFAS and other harmful chemical and dyes in our intimates, here are the certifications we like to look for to ensure we’re putting only the safest and healthiest fabrics on our skin:
- OEKO-TEX® STANDARD 100: This independent certification system tests for harmful substances, including PFAS, ensuring textiles are safe for skin contact.
- GOTS: A textile that is GOTS-certified meets the Global Organic Textile Standard which includes the prohibition of PFAS and environmentally friendly processing.
- Bluesign®: This system ensures responsible chemical use and bans PFAS in certified textiles.
By purchasing your underwear and lingerie from a sustainable brand, you’ll be supporting ethical and eco-friendly brands that put the health of our planet (and our intimate areas!) first.

This super-soft underwear uses certified organic cotton (with a small blend of elastane for longevity and fit) and is finished in certified Fair Trade factories. Don’t sleep on the multipacks and fun patterns!
Customer Review | “I’m truly blown away with the comfort of this fabric. My previous panties weren’t uncomfortable that I was aware of until slipping these on. Wow, seriously feels bare! I’ve gained a ton of menopause mid section weight and originally bought the large based on recommendations (5’2″ 175 lbs – 40 extra lbs all in midsection) but they rolled down over my belly buldge so I sized up to xl and am so very pleased. No moving or bunching. My husband now wants me to order briefs for him” – Angela K. (Read all reviews.)

3. Subset
Best For | Maternity underwear
Materials | Certified organic cotton, elastane, nylon
Size Range | 2XS – 3XL
Prices Start At | $62 for bras, $20 for underwear
Subset (formerly Knickey) makes underwear that puts health first, knowing that millions of us suffer from infections due to toxins found in and on our undies. Instead, the team uses certified organic cotton that’s free from toxic chemicals and carcinogens for its range of thongs, bikinis, briefs, and bralettes. Our editor swears by the supportive keyhole bra (no underwires, and still all the oomph!). And don’t even get us started on the high-rise brief — we wear it straight out of the clean laundry basket, it’s that comfy. Subset takes old undies once they’re ready to be retired and recycles them into new materials like insulation, gifting you 20% off your order as a thank you!
Customer Review | “I was smitten the moment I tried them on! For me, the high waist and cut is better than expected. If it helps others to know – I’m 5’5″ and usually measure around a 28″ waist and 38″ hip, give or take. Hourglass figure. I chose size Smalls and they are perfect. I’m sure Mediums would be comfortable too, but the Smalls don’t even dig in to my sides so I’m not looking to switch. I can also tell how much more breathable the cotton is compared to my old cheaper undies. Quality over quantity. 100% cotton was recommended by my medical professional. The cost is worth it and I am hoping for more color releases!!” – Chelsea G. (Read all reviews.)

Customer Review | “As someone who has chosen to stop wearing underwear for over 6 years, I felt called to give some organic underwear a try. I don’t like feeling constrained or uncomfortable as I do with most underwear. These are the COMPLETE opposite. I literally live in them now, guess I just had to find a pair that wasn’t harming my body and actually complimented it. These do just that. 💫” – Olivia K. (Read all reviews.)

We’ve tried Boody’s racerback sports bra and it’s the one we reach for from our drawer again and again. We recommend it for larger cup sizes for softness and support. In addition to Boody’s underwear, the brand also offers socks, activewear, and children’s clothing. Shop bamboo basics for the whole family!

With soft fabrics and comfortable fits (no riding!), Oddobody is one of our favorite underwear brands for lounging and sleeping. As a PBC, the brand is committed to opening up dialogues about our bodies, so each purchase comes with an artfully made body manual that offers body-related educational content (think: An intro to the pelvic floor, vulva care, and female sexual pleasure) through collaborations with experts. So cool!
