I got intimate with dozens of sustainable underwear and lingerie brands — these are my favorite options made from natural and organic materials by ethical brands.
In 7th grade, I got my first bra. I was so embarrassed about needing one that I stalled as long as I could with tank tops that had built-in ones until my mom insisted on something real. By then, I was a 32B, and what I brought home was shiny and wired. The next day at school, I felt exposed, and a few kids whispered, wondering if I’d stuffed my bra.
It’s funny to look back on that vulnerable moment now as I confidently review eleven bra and underwear brands on the internet. I’m pleasantly surprised by how many supportive, flattering options exist — and how many are made from healthy, sustainable materials instead of the polyester blends I wore in middle school… and let’s be real, into adulthood.
I’ve always heard that good underwear can boost your confidence, but honestly, it’s never been top of mind for me. Before this review, my drawer was basically a lineup of black bralettes and black thongs: A minimalist system that made getting dressed automatic. And the thong thing? Pure practicality. My logic’s simple. If the underwear’s going to end up there anyway, I might as well start there.
But after testing so many “new-to-me” brands, I’m happy to report that I’ve finally found some wedgie-free briefs and colorful bralettes that have officially expanded my underwear horizons. I’m pleased to say, I’m currently wearing a purple set as we speak.
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 help 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.
Turns out, there’s real science behind why breathable, natural fabrics matter. Organic cotton and other plant-based materials help keep things balanced down there: Less moisture, fewer chemicals, and way less chance of irritation or infection compared to the polyester blends that are the norm for conventional underwear.
What should you look for in natural and nontoxic lingerie?
Wearing fabrics without microplastics is especially important for your bras, since synthetic fibers can shed tiny plastic particles that not only irritate sensitive skin but also end up in your body and the environment over time.
The brands I checked out use materials like organic cotton, bamboo, and even OKEO-TEX certified silk. My biggest takeaway? You don’t need synthetics to make fabrics that are soft, luxurious, supportive — and actually comfy.
To help further avoid PFAS and other harmful chemicals 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.
Our criteria:
For my testing process, I wore these sustainable underwear brands everywhere — working from home, to dinner, coffee dates, workout classes, and even on a plane. With bras, I was paying attention to support, shape, comfort, and that all-important “barely there” feel. For underwear, I was on the hunt for no wedgies, no visible lines, and no tight elastic — comfort that makes you forget you’re even wearing them.

1. Pact
Best For | Everyday cotton underwear
Materials | Organic cotton, elastane
Size Range | XS – 3XL
Prices Start At | $35 for bras, $16 for underwear
Pact’s cotton basics help make the world a better place. This ethical brand goes to great lengths to make sure its entire supply chain — from the planting of organic cotton to the final sewing and everything in between — is as clean and responsible as possible. 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!
Editor review: I was genuinely surprised by how flattering Pact’s lace thong set was — the bralette gave me some serious lift! Some lace can feel cheap or itchy, but Pact’s is soft and actually feels good on your skin. I also tried their Everyday Classic Fit Bikini underwear and loved that you can pull them up to make them a little more high-waisted or let them sit low on your hips. The cotton fabric feels breathable and ultra-light, and the elastic doesn’t pinch or feel constricting. I love that they come in an affordable 5-pack for everyday wear.
2. Organic Basics
Best For | Affordable underwear
Materials | Organic cotton, Tencel™ Lyocell, recycled nylon, elastane
Size Range | 32A – 40D, XXS – XXXL
Prices Start At | $30 for bras, $12 for underwear
Organic Basics lives up to the motto of “Basically Better Made” with its incredible everyday essentials. The team first and foremost focuses on sustainable materials — like regenerative organic cotton and TENCEL — as well as ethical production. From bras to briefs, the brand also offers multipacks of its most-loved sets and pieces, so that you can easily make the switch to a more sustainable underwear drawer!
Editor review: Organic Basic’s Core Rib Tank Bralette felt supportive and breathable on a hike — and the website doesn’t mention this, but I’ve even worn it backwards, which gives a slightly deeper scoop neck and looks great! I also tried and love their Core Triangle Bra, which is definitely in my top three favorites. The fabric is soft, there are no clasps, and I love that you can adjust the straps. For underwear, I tried the Core Rib High-Leg Briefs, which give plenty of coverage, and the Soft Touch Veil Thong, which honestly feels like you’re not wearing anything at all.
3. Quince
Best For | Multipacks
Materials | Organic cotton, cotton, modal, rayon, nylon
Size Range | XS – XL
Prices Start At | $25 for bras, $30 for underwear
Quince is all about bringing us the highest quality, all-natural clothing at affordable prices, and they’ve nailed it when it comes to their underwear and bra collections! Crafted with materials like OEKO-TEX certified organic cotton and micromodal, you’ll experience the softest, most breathable fabrics on your delicate regions. Did we mention that their underwear sets start at $30 for a 6-pack?! We’ll be stocking up on these conscious and comfy essentials.
Editor review: I tried the Stretch Lace Sweetheart Bralette in both colors — and I definitely liked it more in black. The tan wasn’t as flattering on my skin tone. The lace is soft and held up nicely in the wash, though I will say the tags are a little bulky and need to be cut off for comfort. For underwear, I tried the Stretch Lace Cheeky Brief – they look and feel beautiful to the touch, but just didn’t work for me. I have a rounder backside, and these gave me an instant wedgie. Would definitely work better on a flatter behind.
4. MATE the Label
Best For | Full-coverage underwear
Materials | Organic cotton, spandex
Size Range | XS – 2XL; up to US 12
Prices Start At | $38 for bras, $28 for underwear
Pesticides and synthetics are a thing of the past with MATE the Label’s intimates collection. The brand crafts its soft and airy undies and loungewear sets with natural and nontoxic materials. Breathable organic cotton and low-impact dyes are used to make MATE’s signature underwear in a variety of flattering cuts and rises. Whether you’re looking for comfy high-rise briefs or a mid-rise bikini, all the pieces are cut, sewn, and dyed in their downtown Los Angeles factory. Not only that, MATE is climate-neutral and ships all their garments in eco-friendly packaging. Score!
Editor review: Mate’s Tencel Wireless Comfort Bra was one of my favorites for everyday wear. It has double-layered support — which you can really feel — because it smoothes and supports nicely under a tee. The adjustable hook-and-eye closure and straps make it feel totally customizable. I also tried the Organic Comfort Scoop Bralette, which is super soft and perfect for lounging around the house. For underwear, the Tencel Comfort High-Rise Cheeky Briefs were too full coverage for me under pants, but they’re silky smooth and great for bedtime. The Organic Comfort Mid-Rise Bikini was another nice everyday basic, made with materials you can feel good about.
5. Embrace
Best For | Maternity, wireless
Materials | Supima organic cotton, micromodal, elastane
Size Range | XS-XL
Prices Start At | $60 for bras, $28 for underwear
Embrace makes nursing bras and underwear that actually feel and look good. The founder, Claire, couldn’t find anything soft, supportive, and made from natural fabrics, so she designed her own — she even spent a full year developing fabric from some of the finest yarns in the world. Embrace uses plant-based materials like US Supima cotton and Austrian Micromodal, skip the underwire, and focus on thoughtful details like padded, convertible straps. The bras also have removable padding for extra support and shape. Everything’s designed with care — from tag-free fabrics to sustainable materials. And they’ve branched out into non-nursing bras and underwear — which I tested and LOVED for this review — that are truly premium and flattering.
Editor Review | Embrace’s Lounge Bra is insanely soft, supportive, and flattering. It gives me shape and lift that I didn’t know was possible without wires. Better yet, the straps are so comfortable, I forget I’m wearing anything. Their High Leg Brief is my new go-to underwear for sleep and lounging – I love that it’s made of breathable 100% organic cotton. It was intentionally designed with a little more coverage, a lower risk of wedgies, and without cutting off your legs – two huge factors for me. I had never heard of Embrace, so I’m surprised that it’s become a top favorite. I even want to order more colors!
6. Araks
Best For | Lingerie
Materials | Upcycled & organic cotton, plant-dyed organic linen, RECONYL, ECONYL®, stretch lace, washed silk
Size Range | XXXS – XXXL
Prices Start At | $90 for bras, $40 for underwear
New York-based brand Araks has been consciously crafting ethical and sustainable lingerie since 2000. Each piece is made locally in their women-owned NYC production facilities (all of which they started!). Araks is intentional about their footprint and fabric usage, ensuring each scrap and swatch is saved for use in future collections. Each of Araks lingerie pieces is also made with high quality, luxury fabrics like cotton crepe from Italy and washed silk from Korea, and uses non-AZO, botanical, or GOTS-certified dyes for rich colors without the synthetics.
Editor review: The Antonia Bralette and Stella Thong make a perfect set – a nice balance of comfortable, feminine, and sexy. If you prefer a brief, the Isabella Panty works beautifully too. Everything is impeccably made by hand, which shows in the details, down to the playful crochet scalloped trim. Araks has tons of fun colorways that feel unique and sophisticated – definitely a great option if you’re looking for lingerie that feels a little more elevated.
7. TomboyX
Best For | Gender-inclusive undergarments
Materials | Organic cotton, cotton, TENCEL™ Modal, recycled nylon, spandex, recycled poly
Size Range | 3XS – 6X
Prices Start At | $24 for bras, $16 for underwear
TGT team favorite TomboyX makes size- and gender-inclusive undergarments so comfy you’ll want to replace your whole underwear drawer. This B-Corp works with WRAP and Fair Labor Association-certified manufacturers and uses materials like Tencel, OEKO-Tex-certified cotton, and recycled polyester blends. (We especially love the Tencel line, it’s so soft!) Whether you’re looking for cute racerback sports bras for working out, boxer briefs for lounging around, or even period and tucking underwear, TomboyX has you covered.
Editor review: TomboyX’s Low Cut Soft Bra was so comfortable, I left it on for the rest of the day the first time I tried it. I even wore it as a sports bra with leggings and an open button-down on a 3-mile walk with a friend. The fabric is insanely soft and feels really well-made. I also tried their Essentials Soft Bra, which is a great high-coverage option. For underwear, I tried the boy shorts — they’re definitely cute, but cut my legs off in an unflattering way, so I’ll be giving them to my sister. I also tried their Tencel black thong, which is just as high quality as the bras… the silky-soft waistband stays put and feels amazing.
8. Oddobody
Best For | Comfy, breathable underwear & loungewear
Materials | Organic cotton
Size Range | XS – XXXL
Prices Start At | $45 for bras, $22 for underwear
The founders of Oddobody created their brand on the single enduring rule their mothers taught them growing up: Underwear should be cotton. The breathable, compostable fabric is ideal for healthy vulvas, so every pair is made from the highest quality, 100% GOTS certified organic cotton. 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!
Editor review: Oddobody’s pieces feel like true cotton classics. Their Mid-Rise French Cut underwear actually makes me feel like a chic Parisian, with elongated legs and a high-waisted front. I also tried and loved their Triangle Bra, which I wore comfortably on a 6-hour plane ride (usually I have to unclasp). Their Shelf Bra is cute and comfy too — perfect for walks, hikes, or gentle yoga. I also tried their Cotton Thong, which is great under jeans. I love that Oddobody’s pieces don’t have big tags or text — just a small, cute emblem of their logo.
9. KENT
Best For | Vegan & plastic-free intimates
Materials | Organic pima cotton
Size Range | XS – 3XL
Prices Start At | $24 for underwear
KENT’s 100% compostable and plastic-free undies are innovation at its finest. The brand uses the cleanest materials on earth and has high standards for each of its basics and undergarments to help reverse climate change. Each plant-based undie is 100% organic, nontoxic, vegan, and “plantable” (right down to the thread). Even the packaging is plant-based and compostable! Once your underwear reaches the end of its life, KENT’s guide on “Planting Your Pants” will have them fully composted in just 90 days.
Editor review: Even before trying Kent, the fact that they’re 100% biodegradable, with no plastic whatsoever, was super intriguing to me. I tried their Organic Supima Cotton Scoop Soft Bra, which has a not-too-thick, not-too-thin feel — it’s soft cotton on the front and back with breathable organic cotton pointelle sides. Their Compostable Organic Cotton Bikini and Thong are comfortable and feel durable. I love that they can be composted, especially since underwear is something you’ll definitely need to replace over time.
10. PROCLAIM
Best For | Inclusive nude lingerie for all skin tones
Materials | Organic pima cotton
Size Range | S – 3X
Prices Start At | $59 for bras, $24 for underwear
PROCLAIM is all about sustainable, ethical, and size-inclusive lingerie and shapewear that feels amazing and treads lightly on the planet. They use earth-friendly fabrics like TENCEL™, organic cotton, hemp, and plant-based EVO® and creora® spandex, ensuring comfort without heavy impacts on the environment. Their commitment to ethical manufacturing means fair wages, safe working conditions, and local production in Los Angeles whenever possible, with additional eco-conscious partnerships in Peru and Portugal. They also minimize waste with smart design, circular knitting, and responsible water use, all while offering an impressive line of nude intimates inclusive to all skin tones. 👏🏻👏🏽👏🏿
Editor review: Proclaim has some great high-coverage options and an impressive range of shades and sizes. Their Organic Cotton Square Neck Bralette feels high-quality and super soft – though the seam in the middle of the bra cuts across the bottom of my chest, which may not bother everyone, but I don’t love. Their Organic Cotton Mid- and High-Rise Underwear feels nicely substantial and holds up well in the wash. I’m excited to try them on my period, since the full coverage is perfect for that.
