The Best Organic & Non-Toxic Clothing Brands For Natural Fiber Wardrobes

Organic clothing is largely a better alternative when compared to clothing made with conventional cotton or fabric that is really plastic (like polyester).

Why? Well, conventional clothing is made with a cocktail of chemicals you’d never knowingly put on your skin, from BPA and PFAS in polyester to formaldehyde in wrinkle-resistant finishes.

Around 60% of fibers produced are synthetic and derived from petroleum, and there are growing concerns around endocrine-disrupting chemicals (and more!) in these textiles. Organic clothing made from certified organic cotton, linen, and hemp skips the harmful pesticides in farming and the harsh chemicals in processing, giving you a cleaner alternative for the fabrics you wear all day.

We’ve pulled together the organic and natural fiber clothing brands we trust most.

What We Looked For

In evaluating the best organic clothing brands for this guide, we prioritized the following (as much as possible):

• Certified organic materials (GOTS, OCS) and natural fibers free from harmful chemical treatments and toxic dyes
• Third-party safety certifications backing up non-toxic claims (OEKO-TEX Standard 100, REACH)
• Transparent, ethical supply chains with fair wages, safe conditions, and third-party audits
• Durable construction and quality we can vouch for from personal wear
• A range of price points from accessible to premium

Our Testing, Ratings & Research

We’ve worn and tested clothing from many of these brands ourselves, in some cases for years. Where we’ve conducted personal reviews, you’ll find them in each brand section below.

For brands we work with through our sustainability rating system, we evaluated their initiatives across 22 criteria including supply chain, labor practices, and environmental commitments. See other rated brands in our sustainable brand directory.

For brands we didn’t rate directly, we conducted careful research to bring you the safest and most sustainable organic clothing brands available.

Health Risks of Conventional Clothing

Most conventional clothing is made from synthetic fabrics like polyester, nylon, and acrylic, all of which are derived from petroleum (unless they are recycled). These materials carry an environmental cost but also carry health risks because of the chemicals used in their production and finishing.

BPA and endocrine disruptors

A 2023 investigation by the Center for Environmental Health found BPA levels up to 22 times California’s safety threshold in sports bras and athletic shirts from major brands. B

PA is a known endocrine disruptor that can mimic estrogen in the body, and it’s commonly used in polyester as a processing aid and dye fixative.

PFAS (“forever chemicals”)

PFAS are added to clothing for water and stain resistance and are especially common in activewear and outerwear. These chemicals don’t break down in the environment or in the human body.

A 2020 review by Kwiatkowski et al. in Environmental Science & Technology documented PFAS bioaccumulation in humans and linked exposure to thyroid dysfunction, immune suppression, fertility issues, and elevated cancer risk.

Chemical absorption through skin

A 2025 study found that textile chemicals can migrate through skin, particularly during sweating. The conditions under which we wear clothing (heat, friction, perspiration) create an environment where chemical transfer from fabric to body is most efficient.

Formaldehyde and finishing chemicals

Formaldehyde is used in some textile finishing processes to make fabrics wrinkle-resistant and colorfast. It’s classified as a known human carcinogen by the International Agency for Research on Cancer. While concentrations in clothing are typically low, prolonged daily skin contact raises the potential for cumulative exposure.

Synthetic fragrances and dyes

Many conventional garments are dyed with azo dyes, which can break down into aromatic amines linked to cancer. Synthetic fragrances added to clothing can contain undisclosed chemicals, including phthalates (another class of endocrine disruptors).

Why Organic and Natural Fiber Clothing Is a Safer Alternative

Organic clothing addresses these concerns at the source. Certified organic cotton (under standards like GOTS) is grown without synthetic pesticides or fertilizers and processed without the harmful chemicals used in conventional textile manufacturing. GOTS prohibits toxic dyes, formaldehyde, and a long list of hazardous chemicals throughout production.

Natural fibers like organic cotton, linen, and hemp are also breathable and biodegradable, which means they don’t shed microplastics during washing the way synthetic fabrics do (assuming they’re not blended with synthetics).

A 2016 study by Napper and Thompson in Marine Pollution Bulletin estimated that a single laundry cycle can release nearly 500,000 microfibers from a polyester garment, contributing to microplastic pollution that has since been found in human blood, lungs, and placentas.

Certifications to look for when shopping for non-toxic clothing include:

• OEKO-TEX Standard 100 (tests the finished product against over 350 harmful substances)
• GOTS (covers the entire organic production chain)
• REACH (an EU regulation restricting over 200 hazardous chemicals)

The Environmental Case

Beyond personal health, organic cotton farming uses significantly less water than conventional cotton. The Soil Association reports that organic cotton uses up to 91% less water from blue water sources (rivers, lakes, and aquifers). Organic farming also avoids the synthetic pesticides that contaminate soil and waterways in conventional cotton-producing regions.

Choosing natural fiber clothing that lasts also means less waste. High-quality organic cotton garments can be worn for years, repaired, resold, and at the end of their life, composted (provided they’re free from synthetic blends, threads, and chemical finishes).

Materials and Chemical Safety

Our top priority was fabric composition. We looked for brands using certified organic cotton (ideally GOTS-certified, which covers the entire production chain from raw fiber to finished garment) and other natural fibers like linen, hemp, and TENCEL™ lyocell or modal.

We paid close attention to how fabrics are dyed and finished, because even organic raw materials can be processed with harmful chemicals.

Certifications like OEKO-TEX Standard 100 and REACH compliance gave us confidence that what ends up against your skin has been independently verified as safe.

Sustainability Credentials & Ethical Manufacturing

For brands we’ve formally rated, we evaluated performance across 22 criteria covering supply chain transparency, climate action, labor practices, chemical management, packaging, circularity, and more.

For brands we haven’t rated, we looked for third-party certifications (B Corp, Fair Trade, FSC), transparent supply chains, and clear commitments to reducing environmental impact.

We prioritized brands with verifiable fair labor practices, whether through Fair Trade certification, WRAP or BSCI audits, or detailed public disclosure of factory locations and working conditions.

We looked for evidence that workers are paid fairly and that workplaces are safe.

Effectiveness and Range

An organic clothing brand is only useful if the clothes are well-made, comfortable, and cover the wardrobe basics you need.

We favored brands we’ve worn and tested ourselves, and prioritized those offering a range broad enough to make a meaningful dent in your wardrobe.

Affordability

We included a range of price points, from Pact’s accessible plastic-free clothes to premium options like Outerknown and The Very Good Bra.

Is organic cotton clothing worth the higher price?

In most cases, yes, because you’re paying for cleaner farming practices (no synthetic pesticides or fertilizers), safer processing (non-toxic dyes, no formaldehyde finishes), and often better labor standards. Organic cotton also tends to be more durable than conventional cotton because the fibers haven’t been weakened by chemical processing.

That said, affordable organic options exist. Pact offers GOTS-certified organic cotton clothes for under $50, and many of the brands on this list run regular sales.

What does GOTS-certified mean?

GOTS (Global Organic Textile Standard) is the leading certification for organic fibers worldwide. It covers every step from harvesting raw fibers through to environmentally and socially responsible manufacturing.

GOTS prohibits toxic dyes, GMOs, and harmful chemicals while enforcing fair labor practices. When a garment carries a GOTS label, the organic content has been tracked and verified from farm to finished product.

Is organic cotton non-toxic?

Organic cotton itself is grown without synthetic pesticides, herbicides, or fertilizers, which means it starts cleaner than conventional cotton. However, fabrics can be dyed, bleached, or finished with harmful chemicals regardless of whether the cotton is organic.

This is why certifications like OEKO-TEX Standard 100 (which tests the finished product for over 350 harmful substances) are important alongside organic certification. The brands on this list prioritize non-toxic processing as well as organic raw materials.

What is the difference between organic clothing and sustainable clothing?

Organic clothing refers to garments made from organically grown fibers, certified to standards like GOTS or OCS. Sustainable clothing is a broader term that can include recycled materials, ethical labor practices, carbon offsetting, circular design, and other environmental commitments.

A brand can arguably be sustainable without being organic (e.g., using recycled polyester) and organic without addressing other sustainability concerns. The best brands combine organic materials with broader sustainability practices.

Is organic cotton better for sensitive skin?

Generally, yes, because organic cotton is processed without the harsh chemicals (like chlorine bleach, formaldehyde, and synthetic dyes) that can irritate skin. Fabrics with OEKO-TEX Standard 100 certification have been tested for substances known to cause allergic reactions.

For people with chemical sensitivities, brands like The Very Good Bra (which is also PFAS-free and plastic-free) or Hahaha (which is OEKO-TEX certified against 350+ substances for safe children’s skin contact) are good starting points.

Can organic clothing be composted?

Some organic clothing can be composted, provided it’s made from 100% natural fibers with no synthetic threads, elastic, or chemical finishes. Unfortunately, most garments contain at least some elastane or synthetic stitching, which means they can’t be fully composted. Always check the full fiber content before putting garments in your compost.

How do I know if my clothing contains harmful chemicals?

The most reliable way is to look for third-party testing certifications. OEKO-TEX Standard 100 tests finished garments against over 350 harmful substances. GOTS certification covers chemical use throughout processing. REACH compliance (an EU regulation) restricts over 200 hazardous chemicals. If a brand doesn’t carry any of these certifications, check whether they publish their restricted substances list (RSL) or disclose their dye and finishing processes.

As a general rule, clothing made from synthetic materials is more likely to contain BPA, PFAS, and other endocrine-disrupting chemicals than clothing made from certified organic natural fibers.

Switching to organic, non-toxic clothing is one of the more straightforward ways to reduce your daily chemical exposure, because unlike food or skincare, most people don’t give much thought to what’s in the fabrics pressed against their skin for hours at a time.

The best option depends on your priorities and budget. For fair trade organic clothing with standout design, Passion Lilie impressed us. For underwear and bras made without a single gram of plastic, The Very Good Bra sets the standard (literally, they’re creating a new standard in Australia). Organic Basics covers the minimalist wardrobe essentials with strong toxicity certifications, while Pact makes the switch affordable for the whole family. And if you’re outfitting kids, Hahaha’s GOTS-certified organic cotton streetwear is a good place to start.

Whatever you choose, replacing even a few synthetic garments with certified organic, natural fiber clothing alternatives will reduce your exposure to BPA, PFAS, and the other chemicals that have no business sitting on your skin all day.
