We’ve lived in organic cotton clothing from sustainable brands for years — these are our favorites that offer a variety of sizes and have lasted the test of time.
Grown without toxic pesticides, fertilizers, or GMOs — all of which are proven to harm the environment, farmers, and producers — organic cotton is a healthier, more eco-conscious alternative to non-organic textile materials. Choosing organic cotton clothing has us feeling comfy as we support sustainable practices — and excited as we stock up our closets with long-lasting high-quality gems we look forward to wearing each and every day!
Why wear organic cotton clothing?
Organic cotton is not only better for our planet and for producers of cotton clothing, it’s healthier for consumers too. Exposure to pesticides can cause a range of health issues — from headaches and nausea to long-term chronic illnesses including cancer, reproductive damage, and endocrine disruption. Organic cotton clothing is also typically more durable because it retains the natural strength of cotton fibers, which aren’t weakened by harsh chemicals used in conventional farming. This means garments last longer, resist wear and tear, and maintain their softness over time. Organic cotton clothing farming is also more sustainable, as it avoids toxic pesticides and synthetic fertilizers, reducing soil and water contamination. By using crop rotation and natural composting methods, organic cotton farms support biodiversity, improve soil health, and use less water, making organic cotton clothing the preferred choice for the betterment of our health, wellness, and sustainability of the planet.
What should you look for when shopping for organic clothing?
When shopping for organic clothing, look for certifications like GOTS (Global Organic Textile Standard) and OEKO-TEX, which ensure that fabrics are free from harmful chemicals and produced using eco-friendly methods. It’s also important to consider ethical labor practices — brands committed to fair wages, safe working conditions, and transparency in their supply chain will often have certifications like Fair Trade or WRAP (Worldwide Responsible Accredited Production). Beyond fabric, check if the brand uses low-impact dyes, plastic-free packaging, and sustainable production methods to minimize environmental impact. Choosing organic clothing isn’t just about the fabric — it’s about supporting ethical and responsible fashion from start to finish. 🌿

Our Editor’s Review | “Pact’s leggings are tight, the way the best kind of hug makes you feel safe and calm instead of squeezed and breathless. They are super soft, like baby skin soft, which means I want to wear them for my morning run, the walk to the dog park, the carpool, the grocery store, sitting at my desk, making dinner, and lounging on the sofa. ” – Trinity Wilbourn, Contributing Editor [Read the full review.]

The packaging is entirely made from recycled materials, and there’s a recycling program in place for old pieces. If you want comfy classics in bold yet inviting colors, look no further than MATE.
Our Editor’s Review | “As someone who lives in her “cozies” year-round, MATE the Label’s organic basics are my cozy garments of choice — for lounging at home or running errands around the city.

For capsule wardrobe worthy pieces, Kotn is your go to.
Our Editor’s Review | “Starting off strong with this mock tank! I must confess, this is a favorite silhouette for me — anything sleeveless with a high neckline is immediately considered for purchase. That also makes me a connoisseur of this type of shirt, and Kotn’s is one of my favorite versions. The fabric is a thick, 100% cotton knit that doesn’t feel suffocating even on really hot days. I also love the thickness because I feel held in by it.” – Ashley D’Arcy, Senior Editor [Read the full review.]
