The best sustainable clothing brands prove great style doesn't need to cost the environment. As we become increasingly aware of the detrimental impact fast fashion shopping habits have on the world we live in, the demand for brands that put the planet before profit is growing. 

It's now easier to shop more sustainably than ever as the industry rapidly grows due to consumer demand. While sustainable clothing used to carry a hefty price tag, it's becoming increasingly more price-accessible. Whether you're looking for luxe t-shirts, jeans, or even footwear all can now be updated with slow fashion and sustainable alternatives.

It's no secret that the fashion ecosystem has contributed to the ever-growing climate crisis while compounding existing environmental, labor, and social injustices. The fashion industry produces 10% of humanity’s carbon emissions, emitting more than international flights and maritime shipping combined. Not only this, fashion production is the second-largest consumer of the world’s water supply, and washing synthetic fibers causes microplastics to enter our oceans and harm marine life. 

“Sustainability in the fashion industry is not just important, it's vital," says Charlie Bradley Ross, Founder & Director of Offset Warehouse & The Sustainable Fashion Collective. That's why we always turn to the best sustainable clothing brands when shopping for new pieces to add to our closet.

The best sustainable clothing brands as chosen by our fashion team

“With systemic change, the fashion industry can lift millions of people out of poverty, providing them with decent and dignified livelihoods. It can preserve and restore our living planet. Fashion can be a powerful force for good - bringing people together as a source of joy, creativity, and expression.” says Bradley Ross. From up-and-coming labels to well-loved names, these are the very best sustainable clothing brands to shop now.
