Sustainable Women’s Clothing: 18 Best Ethical Clothing Brands For Women In 2023

sustainable women's clothing

Can you look fashionable and make an environmental difference at the same time? Yes! Sustainable women’s clothing allows women to be both stylish and responsible. 

Why does that matter, you ask? The fashion industry is one of the biggest polluters in the world thanks to the fast fashion model. Billions of pieces of low-quality clothing are bought and discarded every year. As a result, the US alone produces 17 million tonnes of textile waste annually.

This is where slow fashion comes in. Slow fashion brands make high-quality, long-lasting, eco-friendly, and biodegradable clothes. The best sustainable brands use eco-friendly fabrics and production to make fashionable clothing for women.

To join the movement towards a better future, read on.

Honorable Mentions For Sustainable Women’s Clothing Brands

What Makes Clothing Ethical and Sustainable

Multiple factors make sustainable women’s clothing stand out from the crowd. The main ones are:


Women’s sustainable clothing can’t be made from just any fabric. Some fabrics like polyester and nylon are entirely synthetic and don’t biodegrade. Others, like cotton and wool, while natural, require copious amounts of water, land, and energy. 

The best sustainable fabrics are natural and organic fibers like organic cotton, hemp, bamboo, organic linen, organic silk, organic wool, and more. This is because the fibers are made without excessive water use and synthetic chemicals like fertilizers. 

Semi-synthetic fibers like lyocell, modal, and viscose are also acceptable as, compared to conventional fabrics, they reduce the negative impact on the environment. Recycled fabrics are also excellent choices. 

There are numerous third-party organizations whose sole purpose is to ensure that clothing brands follow strict production standards. So, look for certifications like Global Organic Textile Standards (GOTS), OEKO-TEX Standard 100, SA8000, Bluesign, National Organic Program (NOP), B Corp Certification, and more.


What’s the point of sustainable women’s clothing made with the best fabrics if the brand lacks good ethics? Eco-friendly clothing brands must ensure workers receive proper compensation and a safe working environment. 

To ensure that a brand is doing just that, look for certifications like Fair Trade, Fair Labor Association, USDA-Certified, and more.
