Shopping for sustainable fashion is one simple way to make a big impact. By choosing eco-friendly clothing brands, you’re supporting a greener planet and enjoying peace of mind with every purchase.
Sustainable clothing brands commit to ethical practices and produce safe, toxin-free clothing—and we’re spoiled for choice. Explore this guide and discover the best environment-friendly clothing to expand your wardrobe and minimize your fashion footprint.
Sustainable clothing is made by ethical brands that apply fair labor practices, reduce chemical use, and use low-impact materials, such as 100% organic cotton and recycled textiles. These companies also promise supply chain transparency to ensure positive worker conditions and fabric sourcing.
This production process is costly, so affordable sustainable clothing can be challenging to find unless you’re shopping secondhand. Businesses that prioritize a steady, careful approach to clothing manufacturing are often called “slow fashion brands,” highlighting a direct contrast to the common fast-fashion model.
Eco-friendly clothing companies are paving the way to a more mindful fashion industry. Here are fifteen of our favorite sustainable fashion brands to shop for so you can join this movement.
