15 best sustainable clothing brands to shop in 2024 | CNN Underscored

Sustainable living isn’t easy. Whether you’re composting at home or using recyclable and refillable beauty products, reducing your environmental impact takes extra thought and time. But it doesn’t always have to be time-consuming or tedious. One fun and easy switch you can make today: Ditch fast fashion and shop sustainable clothing brands. Sure, sustainability has become somewhat of a marketing ploy for many companies in the style and fashion world. But we talked to experts to figure out what brands are actually green and what you should look for when trying to shop for sustainable fashion.

So what exactly does sustainable fashion mean? “Sustainable fashion usually means eco-friendly practices in the fashion industry, referencing the approach of designing, producing and consuming clothes that respect the planet by causing little to no damage, and therefore sustaining the environment,” says Katrina Caspelich, the chief marketing officer at Remake, a nonprofit fighting to end fast fashion. “At Remake, we define this term holistically by looking at both the planetary and human impact, defining sustainable fashion also as the industry’s practice of sustaining the healthy lives of the people who make our clothes through living wages, safe work conditions and maker well-being.”

But before you even research clothing brands for eco-friendly practices, know that wearing what you already have or buying secondhand is the most sustainable thing to do. “The best way to practice sustainability is by shopping your closet before purchasing anything new,” says Caspelich. She also recommends checking out vintage, rental and consignment stores or “shopping” your friends’ closets before you buy brand-new clothes.

If you’ve exhausted all those options and still want to buy new, the good news is that there are tons of brands taking initiatives to make more sustainable clothes, whether that means using recycled materials, lowering carbon emissions in manufacturing or paying workers fair wages. However, Caspelich says you can’t always trust brands that claim to be eco-friendly. “Where many individuals wish to make meaningful change in their purchasing choices, marketing heads of fashion companies use greenwashing, manipulative tactics to make sales, without doing the hard work of running a truly sustainable company,” she says.

Avoiding these marketing ploys and giving your money to companies that are actually taking strides to become sustainable can sometimes be hard, but Kimberley Smith, chief supply chain officer at Everlane, has a few tips to help you find well-intentioned brands.

“Consumers should look for brands that put an emphasis on transparency in their supply chain. There is no regulation of the word ‘sustainable fashion,’ and in an industry that is already opaque, some brands can be dishonest about their environmental impact,” says Smith. “It’s also important to keep an eye out for partners and standardized certifications that can support sustainability claims. For example, The Global Organic Textile Standard (GOTS) for organic cotton, Global Recycled Standard (GRS) for recycled products, the LEED certification for reduced energy consumption in factories or Bluesign for chemical and environmental management.” It’s also good to look for certified B Corporations, which meet a strict set of standards measuring a company’s environmental impact.

Elizabeth Cline, author of “The Conscious Closet: The Revolutionary Guide to Looking Good While Doing Good,” echoes many of Smith’s tips. “Keep in mind that the vast majority of fashion’s impact happens in manufacturing, so the area where brands are doing the most work to be green is in the materials,” she says. “So to choose a more sustainable option, start by looking more closely at the fabrics brands are using.” Cline also says to remember that sustainable fashion goes beyond brands. “You don’t have to buy anything to be involved. Resale, shopping thrift, caring and mending the clothes you already have and throwing a clothing swap with friends are all easy ways to be green and fashionable. What’s more, sustainable fashion often starts with a shift in mindset.”

As you can see, there’s a lot of research to do when making the switch to sustainable fashion. But if you don’t want to spend hours digging through the “About” sections of dozens of brands, there are resources such as Remake’s Sustainable Brand Directory and the site Good On You, where you can search for specific brands to see their environmental impact.

To give you a head start, we’ve compiled a list of sustainable shoe and clothing brands that put sustainability at their forefront, some of which come recommended right from our experts.

Caspelich recommends Girlfriend Collective as a great option for activewear, bras and underwear as well as a few outerwear pieces.
