As we talk more about sustainability, we’re also rethinking what really makes clothing “better.” In 2026, non-toxic fashion means more than just catchy phrases or recycled claims; it starts with the materials our clothes are made from. The fabrics we choose matter for our health, the environment, and how long our clothes last, but this is often ignored in favor of trends & marketing. This guide highlights brands that use natural fabrics, cleaner ways of making clothes & ethical practices, so you can build a wardrobe that feels good, matches your values & helps people and the planet 🙂

What fabrics should you look for when purchasing new clothes?
When you want non-toxic fashion, what your clothes are made from matters. In 2026, we look for fabrics that come from nature, are grown responsibly, and are made with fewer harmful chemicals. These kinds of materials are better for you & the planet.
Natural & Plant-Based Fibers We Prioritize
- Organic Cotton: This cotton is grown without toxic chemicals or fake fertilizers. It’s safer for farmers, the environment, and your skin. If you can, look for GOTS-certified organic cotton.
- Linen: Linen comes from the flax plant and doesn’t need a lot of water or chemicals to grow. It’s breathable, strong, and breaks down naturally.
- Hemp: Hemp is a super sustainable fiber. It grows quickly, helps keep the soil healthy, and requires little to no pesticides.
- Wool & Alpaca: These natural fibers help keep you warm or cool, last a long time, and break down safely when sourced sustainably.
- Silk: Silk is a natural fiber made by silkworms. When made ethically, it’s strong and soft, and doesn’t need fake additives.
Fabrics We Are More Cautious Of
Semi-synthetic fibers like TENCEL™ Lyocell, Modal, and viscose are somewhere between natural and fully synthetic materials. They come from plants, like wood pulp, but still need chemicals to turn them into fabric. Because of that, we see semi-synthetics as a second-best choice. They’re better than plastic-based fibers, especially if they’re made in factories that handle chemicals well. But they aren’t as good as real natural fibers. If you pick carefully, semi-synthetics can be soft and work well, and they can be better for the environment. Still, we prefer natural fibers that undergo less processing whenever possible. Lyocell, which can be made from either bamboo or eucalyptus, is the best option for semi-synthetics.
What We Limit
We try not to buy synthetic fibers like polyester, nylon, & acrylic (even if they’re recycled) because they can shed microplastics, rely on fossil fuels, and might expose you to chemicals. Synthetics can be useful for special sports clothes, but they’re not our first choice for everyday outfits anymore. Also, sometimes we need a little stretch, and synthetics are blended with natural fibers. Our rule of thumb is to keep synthetics to less than 15% when purchasing a new piece of clothing.
