Best sustainable clothing brands 2021: 40 ethical fashion lines

Dress for success this year — for yourself and for the future of the planet.

Fast fashion is fun, but it’s time to slow it down and really consider the environment when shopping for new clothes and accessories. With so many sustainable and eco-friendly brands flooding the market, it’s not hard to budget for the health of the eco-system while you shop. But, it doesn’t have to be expensive.

“Ethical” and “sustainable” can be confusing terms, as they mean different things for different brands and shoppers. To put it simply, sustainable practices may involve making the dyes from eco-friendly materials that are chemical-free, using renewable energy in the production process, using durable fabrics so clothing lasts as long as possible and recycling old materials like scrap fabric and even plastic bottles into new garments. Basically, the less harm to the planet, the better.

From single-origin cashmere sweaters to fully recycled shoes and accessories, you can rock responsible outfits, head-to-toe, no matter your style or price range. Take a look at the top 40 brands for her, him and anyone who values Mother Nature every fashion season of the year.
