The Best Organic Underwear & Bra Brands

When we speak about sustainable fashion and clothing, one of the most preferred options would be thrifting, recycling and reusing.

But, the thought of wearing used underwear, or a bra is not the most sanitary.

A more mindful choice is organic bras and underwear.

The good news is that there are many sustainable brands that use natural dyes and eco-friendly materials, but let's talk about the importance of organic, first.

What does organic and ethical mean when it comes to your undies and bras and why should we care about what's in our underwear drawer? 

The first thing you need to know is that organic undergarments are made from organically farmed cotton, bamboo, hemp or other natural fibers, that are grown without the use of harmful pesticides or other toxic chemicals. And, just like organically farmed food, organic fiber crops are better for the environment.

Why Shop Organic Underwear?

These are a few reasons to choose organic fabrics when shopping for underwear!

Prevents Bacterial Growth: Panties made with organic cotton are breathable, which means it prevents the growth of bacteria and yeast infections. It’s reported that synthetic materials can cause an imbalance of yeast and bacteria leading to a yeast infection.

More Comfortable: If you have ever worn organic inner wear, you can instantly feel the difference. Because organic cotton is handpicked, it tends to be softer as it preserves the length of its fiber over machine-picked cotton. 

Supports Ethical Companies: Ethical companies go through a lot of effort, all the way from sourcing organic to sustainable logistics and then to equal labor rights. So, when you buy from them, you are able to support your values of ethics and sustainability.

What’s wrong with conventional undies?

Plastic is the key ingredient in the average conventional panties. Anything made with polyester has plastic in it, because polyester is made from polyethene terephthalate, which is essentially PET plastic woven into fabric.

Also, polyester cannot be recycled and is not biodegradable. Elastane is a culprit too. So, your old undies are likely not made with the most sustainable materials.

On top of that non-organic cotton may contain pesticides and other toxic chemicals. Non-organic materials are grown using chemical fertilizers that are applied to crops.

Certain chemicals have been linked to health issues such as hormonal disruption, allergies, and cancer. 

What materials can be organically grown? 

These are some materials to keep your eyes open for when shopping for new bras or underwear.

  • Cotton: Organic cotton fiber is made up of natural cotton seeds, rather than processed ones. It is devoid of toxic pesticides, synthetic fertilizers, or genetically modified seeds (GMOs) and it follows organic processes in growing and textile manufacturing processes, which further increases the quality of cotton substantially. It also smells fresh and feels very soft. 

  • Bamboo: Bamboo is a fast-growing, regenerative crop that doesn’t require fertilization and is often touted as a sustainable material when mechanically processed (otherwise known as bamboo linen or bast fiber). 

  • Hemp: Hemp does not require pesticides or fertilizers to grow. It does not exhaust the soil but releases nutrients into the soil. It is mostly used as an alternative to organic cotton as its fabric is non-irritating to the skin. Hemp does not require a certification because it is inherently organic, but if a certain brand claims it, then check if it has 100% hemp mentioned, not just hemp fibers. Hemp softens after every wash, is very durable and has UV-resistant qualities. 

  • Linen: Linen is created from flax fibers, which do not require any fertilizer. Also, flax can be used as crop, oil, or seed due to which there is no waste. Linen is slightly expensive because of its certification. 

3rd party certifications to look for

When shopping for new underwear consider looking for these third party certifications.

  • Fair trade: Fair trade ensures that factory workers are paid livable wages and have safe working conditions.

  • GOTS: Global Organic Textile Standard (GOTS) is the worldwide leading textile processing standard for organic fibres, including ecological and social criteria, backed up by independent certification of the entire textile supply chain. GOTS certified final products may include fibre products, yarns, fabrics, clothes, home textiles, mattresses, personal hygiene products, as well as food contact textiles and more.

  • OEKO-TEX: This label certifies that every component of the product, from the fabric to the thread and accessories, has been rigorously tested against a list of up to 350 toxic chemicals.

  • BCI: The Better Cotton Initiative (BCI) is a holistic approach to sustainable cotton production which covers all three pillars of sustainability: environmental, social and economic.

  • B Corporation: Certified B Corporations are leaders in the global movement for an inclusive, equitable, and regenerative economy.
