How We Found The Best Organic Cotton T-Shirts

When it comes to sustainable and ethical fashion, organic cotton is a popular choice. However, not all organic cotton t-shirts are created equal. To find the best organic cotton t-shirts, the following factors were considered:


The best organic cotton t-shirts are made with cotton that is grown in a regenerative way that supports a healthy ecosystem and climate. Additionally, the use of natural, non-toxic, and low-impact dyes is preferred. Some brands also blend organic cotton with other eco-friendly fabrics like TENCEL lyocell or modal, or hemp. It is also worth noting that organic cotton requires 91% less water than conventional cotton, making it an eco-friendlier choice.


Certifications like OEKO-TEX® 100, PETA, GOTS, Fair Trade, and GRS ensure that the organic cotton t-shirts are made with sustainable and ethical practices. Brands that support garment workers with fair trade pay, reasonable hours, supportive work conditions, healthcare, and more are also preferred.

Green Business Practices

The best organic cotton t-shirts are not just made of sustainable materials, but also produced in an eco-conscious way. This includes using recycled water, renewable energy, and eco-friendly packaging. Some brands are even carbon neutral and designed to last, reducing their environmental impact.


Inclusivity is also an important factor in finding the best organic cotton t-shirts. Brands that offer gender-neutral styles and a relatively inclusive size range are preferred. It is also important to support BIPOC or women-owned brands, use inclusive marketing, and adopt ethical plus-size fashion offerings.

Community & Charitable Giving

Brands that donate a portion of their sales, support farming/textile communities, donate fabric scraps and used garments, and support people experiencing disabilities or disadvantages are preferred.

Final Thoughts On Organic Cotton T-Shirts

Organic cotton t-shirts can be a great choice for the environment and the people who produce them. However, it is important to consider whether a new t-shirt is really necessary before making a purchase. Checking local or online thrift stores first, or wearing what is already in your wardrobe, can be a more sustainable option. By choosing to wear better t-shirts, we can all contribute to a thriving planet.
