We all know that fast fashion takes a huge environmental toll—from the pollution created during the manufacturing process to the way it fuels our "haul culture," filling closets with barely-worn clothes that ultimately end up in landfills. Whew, it’s a lot! So major kudos to you if you plan on shopping greener here on out. But before you stress about overhauling your entire closet or regretting past fashion choices, know that shifting to sustainable brands is easier than you think—and totally worth it.

As a shopping editor (so, basically, your personal shopper here at Cosmo), trust me: you don’t need to get rid of everything you own (that’s actually wasteful). It’s about making mindful choices and gradually transitioning to brands that align with your values—ones that prioritize fair wages, eco-friendly materials, and sustainable practices. So, thrift, vintage shop, rent, and treat every day like Earth Day by wearing the 22 sustainable and eco-friendly brands we’ve rounded up below.

You’ll also find quick tips on how to spot truly ethical and eco-conscious brands because let’s be real, navigating greenwashing can be tricky. Not all brands are eco-friendly like they advertise to be! But don’t worry, we’ve done the homework for you, so think of this as a shopping guide and an educational resource for ethical fashion shopping tips.

This adorable Girlfriend Collective workout set? Oh yeah, it's made from recycled water bottles—and it comes in an extended size range that flatters and supports every body shape and size. Though functional enough for the gym, the Seattle-based activewear brand's ethically-made, eco-friendly sets are so cute you'll want to wear them everywhere.

There's no excuse for buying fast fashion when you can grab eco-conscious, responsibly sourced styles at Everlane for pretty much the same price. What truly sets the brand apart from others is its transparent pricing. While most remain tight-lipped about what they pay for labor and materials, Everlane puts it right on the product page. See for yourself!

Reformation's lengthy list of celebrity fans includes—clears throat—Taylor Swift, Olivia Rodrigo, Emma Watson, Kendall Jenner, Jisoo, Selena Gomez and last but certainly not least, Sarah Jessica Parker. The It-Girl brand has dresses, jumpsuits, and matching sets for every occasion. Need I say more?

Making eco-friendly fashion choices doesn't require going full granola or going broke, and Warp + Weft is proof. While a typical pair of jeans takes around 1500 gallons of water to produce (crazy, right?), Warp + Weft's take less than 10 gallons thanks to its innovative water recycling and dying techniques. Best of all, cute styles like these flare-cut jeans come in plus sizes, too.

PACT is the place to go if you're looking for affordable, eco-friendly clothing that you can wear season after season. The brand has sundresses, button-ups, loungewear, bras, undies, you name it—and there's a good chance you can score your new carbon-neutral cuties on sale.

Founded in 1973, Patagonia walked so that all those cute outdoorsy sets on your IG feed could run. Despite all the trendy sustainable brands that have come along over the years, Patagonia's retro fleece pullovers and puffer jackets (made from recycled polyester) are still the crème de la crème. Treat yourself to one now, and you'll be wearing it for decades to come. Plus, you'll be helping the brand fund grassroots environmental groups.

Farm Rio's bold prints and interesting design details make its statement pieces the type you keep for life. Based in Rio de Janeiro, Brazil, the boho-chic design collective is doing its part to preserve local rainforests by planting a tree for every item purchased. Plus, the certified B-corp prioritizes eco-friendly materials and transparent supply chains. All to say, your cute new statement piece is a net positive.

DL1961 is a sustainable denim brand that has an innovative ~waterless~ system that uses less than 10 gallons of water per pair of jeans—98% of which is recycled through an in-house treatment plant. To further reduce waste, DL1961 uses recycled fabrics from old jeans, which is why fashion legends like Anne Hathaway, Gigi Hadid, and Jennifer Lawrence are fans of the brand!

LA Relaxed's sustainability efforts go above and beyond using organic cotton (as they should!). The LA-based brand's high-quality basics are locally produced in small batches using deadstock (read: leftover) fabrics and eco-friendly materials from well-vetted suppliers. Eliminating international shipping altogether makes the carbon footprint of these cute tees and tanks teeny-tiny compared to other brands, especially fast fashion giants.

Veja sneakers are like catnip for eco-conscious celebs and Cosmo editors alike (Taylor Swift, Kourtney Kardashian, Lily Collins, Kate Middleton, Katie Holmes, and Veja's other famous fans are onto something). While most sneaker brands rely on petroleum-based synthetic rubber and polyester, the fashion B-corp makes its shoes with responsibly sourced Amazonian rubber, organic cotton, and recycled polyester. Plus, they're so transparent about where they source their materials and make their products.

There's a v good chance you've already seen Marine Serre's signature crescent moon print on your social media feed, as it's been worn by everyone from Bey to Kylie J. The 2017 CFDA Award winner is undoubtedly one of influencers' and celebs' fave sustainable fashion brands, thanks to her focus on upcycled and eco-friendly materials. It doesn't hurt that Marine Serre's second-skin bodysuits and patchwork prints feel right on trend for 2024, either.

Warning: Once you start wearing KOTN, you won't want to wear much else. The certified B-corporation's minimalist styles strike just the right balance between trendy and timeless. You'll be obsessed with them now, next year, and a decade from now.

The brand describes its transparent supply chain as "farm to table for your clothes." Meaning that the cute linen blazer or cotton tank you just added to your cart is helping create stable, fair-paying jobs on small farms in Egypt and fund education in these communities. A real win-win.

In a world where every brand makes sweatshirts and sweatpants, Panagia sweatsuits are still the gold standard—and who could forget when Harry Styles broke the internet in his hot pink Pangaia hoodie! The B-corp's casual basics are made using traceable, regenerative cotton in factories that prioritize garment workers' health, and they come in a rainbow of mix-and-matchable color options. This 365 hoodie and track pants combo (offered in both midweight and heavyweight cotton) will be your go-to set for years.

Hyer Goods is giving handbag girlies something to celebrate. To reduce textile waste, the sustainable accessories brand uses deadstock leathers and leftovers from the luxury handbag industry to create its timeless everyday styles. Your cute new bag will look and feel just as ~expensive~ as any big-name designer brand, but it'll have a far smaller carbon footprint.

No outfit is truly complete without a touch of sparkle, which is why I couldn't help but include the sustainable jewelry brand Ana Luisa as one of my eco-fashion faves. From everyday studs to solid gold hoops, every Ana Luisa piece is made using ethically sourced materials. Just as importantly, the company regularly audits its factories to ensure fair working conditions, and it offsets its carbon emissions, too.

No fabrics in our polyester-filled world are more luxurious than true silk and cashmere. Sustainable silk and cashmere are Lilysilk's specialty, and they're picky, picky, picky when it comes to suppliers.

Over the past few seasons, they've become a cornerstone of my closet. So much so that the brand is one of the first I rec to friends searching for sexy slip dresses and keep-forever layering pieces. They advocate for "zero waste, zero scraps and zero leftover inventory," so how can I not?

Meet your next obsession: Outerknown. The fashion brand prides itself on its ethical production practices and sustainable fabric choices, partnering with B-corporations and non-profits to make your purchase even more impactful. Known best for its casual button-ups and tees, you can find all sorts of hidden gems like this terrycloth matching set ahead of summer.

It's all too easy to forget that the clothes you wear are sewn together by real people with real hands—but not if you shop at Cleobella. Artisans are the heart and soul of the brand, as is sustainability. From swimwear and beach cover-ups to work blouses and wedding guest dresses, every ethically made style helps fund STEM courses for young women, remove ocean plastic, and plant trees through Cleobella's various partnerships with global non-profits.

Sustainable fashion wouldn't be what it is today without Stella McCartney. A longtime vegetarian, she's paved the way with her responsibly sourced cashmere and forward-thinking, eco-conscious leather alternatives. Her clothing, handbags, and shoes are certainly an investment, but a worthwhile one for any eco-conscious cool girl who's ready to splurge on a designer piece. Anything you score from Stella McCartney (or her popular Adidas collab) has the style and quality to last a lifetime.

I'm a sucker for Naadam cashmere sweaters. Not only are the yarns they use really, reallllyyyy soft, but they're also sourced directly from traditional Mongolian herders (who often get screwed over by middlemen) to ensure they earn a fair wage. Lucky for us, Naadam's close relationship with its suppliers also helps shoppers score designer-quality cashmere at a much more reasonable price.
