If you're searching the Internet for sustainable clothing brands, chances are, you're keen to cut down on your fast fashion consumption and make your wardrobe a little more eco-friendly.
Shopping ethically is a great way to reduce your carbon footprint and overall emissions, especially now that more and more brands are focusing on producing better quality clothes with a seasonless aesthetic, meaning customers won't grow tired of them after a few months.
But with so much sustainable fashion around, knowing how to pick the right brands can be tricky, especially when so many are guilty of greenwashing. With that in mind, here at Marie Claire we've put together a guide to help you, including some of our favourite B Corp brands that need to be on your radar.
What is the difference between ethical and sustainable clothing brands?
There is a lot of confusion between the terms 'ethical' and 'sustainable.' No, the two aren't the same. Treating staffers, suppliers and so on in an ethical manner is just one part of being a sustainable business.
There are different ways to produce ethical clothing, and according to the Ethical Fashion Forum, they generally fall into three categories - social, environmental and commercial. The forum specifically tackles these issues:
- Countering fast, cheap fashion and damaging patterns of fashion consumption
- Defending fair wages, working conditions and workers’ rights, and supporting sustainable livelihoods
- Addressing toxic pesticide and chemical use, using and/or developing eco-friendly fabrics and components
- Minimising water use
- Recycling and addressing energy efficiency and waste
- Developing or promoting sustainability standards for fashion
- Providing resources, training and/or awareness-raising initiatives
- Protecting animal rights

What constitutes a sustainable clothing brand?
When it comes to sustainable fashion brands, there are many things to consider including how a brand sources its fabrics, how they manufacture and transport their products, and how they sell items in a planet-friendly way.
As Joanna Dai, founder of the B Corp-certified clothing brand Dai shares, every new product put out into the world has an impact - however, some brands are doing better than others to minimise their mark. We asked Dai for her expertise on how you can ensure a brand is genuine in its sustainability efforts.
How can you spot if a brand is genuine in its sustainability efforts?
Joanna Dai outlines her tips below.
Accountability - "For real change, brands must be accountable for their impacts and decisions across the entire business," she shares. "Brands that achieve B Corp certification are invested in running a responsible business."
Fabrics - "Look to brands that are using certified plant-based or innovative recycled materials as much as possible," she recommends.
End of life - "Sustainability doesn’t end once the customer checks out their basket. Look out for brands that offer repairs and take-back schemes that help increase a garment’s longevity or encourage responsible recycling," she encourages. "We recently introduced Dai’Cycle, a programme where customers can drop off their preloved Dai clothing in exchange for a £25 gift card to use on their next in-store purchase. We will renew and repair the donated pieces and offer them in-store as preloved items to new customers, or donate it to our charity partner Smart Works."
Building products to last - "Alongside an end-of-life programme, invest in brands and products that are well designed and built to last," she goes on. "This is a founding principle at Dai, I personally road-test each and every product to make sure it performs and functions for our customers now, and for years to come."
Valuing people - "Sustainability must combine people and the planet. Look at brands' supplier codes of conduct or commitments to paying fair and living wages to ensure the people who are making your garments are being treated well."
Marie Claire UK's Sustainability Editor, Ally Head, agrees, adding that shopping for sustainable clothing can feel like a minefield when you've got brands greenwashing left, right and centre.
Her advice? "Always check whether a brand has a B Corp certification. If they do, it means they've undergone the most rigorous testing - qualifying can take as long as three years (!) - to make sure their practices are plant-friendly across all aspects of their business. They have a detailed directory on their site of all the brands that have qualified."
Secondly, do your research - often, if a brand actually works to sustainable practice, they'll have a whole page dedicated to it on their website. "Do read up and also carefully consider both the eco-claims they are making and how they say their business is structured - do they promote fast fashion, do they rack up air miles like there's no tomorrow, and do they still send products out in non-recyclable or non-biodegradable materials? Even if a brand says they're sustainable, they might be greenwashing - for example, a global company that churns out new designs every day doesn't *sound* sustainable to us."
And thirdly, use your common sense. "Buying secondhand, shopping in vintage stores, using pre-loved fashion sites or renting clothes are all great ways to shop sustainably and lower the impact that creating new clothes can have on the environment," Ally explains.

The best sustainable clothing brands you need to know about:
Rise&Fall is a B Corp certified brand, making clothing and bedding from high quality fabrics including a-grade cashmeres, organic extra-long staple cottons, mulberry silks, European flax linens, and Mastrotto leathers.

They get a good price for their products, which means they can look after their people, and Rise&Fall deliver true luxury items at a reasonable price point.
Editor Verdict:
"Rise&Fall is one of my all-time favourite brands. I have multiple clothing items, bedding, and even pillows from here, and the quality of every piece is second to none. I love that every design is truly timeless, increasing its longevity in my wardrobe even more, and each material is truly luxurious—but not outrageously priced. I rave about this brand to anyone who will listen." - Amelia Yeomans, Junior Shopping Editor
OMNES means all, with the brand's ethos being that we are all in this together. The B Corp brand is aware that fashion is one of the worst polluters, so even when sketching clothes, designers think of styles and fabrics that you will wear as long as possible. The brand also uses offcuts in accessories to minimise waste, and audits its factories in Romania, India and London to make sure they comply with Health and Safety, Environment, Business Ethics and Labour Standards.
Editor Verdict:
"When it comes to chic dresses and understated event wear, Omnes is one of my favourites. I love the brand's signature cowl neck slip dresses, which are often made from recycled polyester, Ecovero Viscose or deadstock fabric. The shapes are so flattering and they're the kind of dresses you can wear for years to come for all manner of different occasions." - Zoe Anastasiou, Fashion Editor
Ninety Percent gained its name thanks to its unique business model, which sees the brand sharing 90% of its profits between its people and charitable causes that prioritise the planet. In addition to this, the brand also prides itself on transparency and traceability, as well as the use of sustainable materials.
The label focuses on the use of natural, renewable and certified organic materials, including Linen, ENKA Viscose, Tencel, Micro Modal and Global Organic Textile Standard (GOTS) certified organic cotton. And also uses low-impact finishes like plant-based buttons and nickle free metals.
Dora Larsen’s bespoke laces are designed on an exclusive basis, and all are made using at least 83% recycled materials – 2/3 of their laces are produced in a workshop that uses solar power to provide full capacity electricity and water recycling units to monitor and limit water consumption throughout the dying process. All the brand’s material and component suppliers, as well as their dyehouses, meet REACH standards and their materials are also OEKO-TEX certified, meaning they’re non-toxic and free from harmful chemicals. Collections are made in limited quantities to avoid leftover stock each season, and the brand’s FSC-certified paper and cardboard packaging is made from a blend of sustainably sourced, replanted trees and recycled materials, and is also fully recyclable or compostable

Editor Verdict:
"Dora Larsen underwear is some of the most chic on the market, so it's a huge bonus that each piece is sustainably produced. Plus, the quality is excellent, so it's worth every penny." - Amelia Yeomans, Junior Shopping Editor.
Founded in 2025 by Amy Powney, former creative director of Mother of Pearl, AKYN is a contemporary womenswear label that focuses on timeless, beautifully-crafted pieces with care for the Earth at the forefront. With an aim to be the most responsible and traceable brand, AKYN is built on a regenerative-focused business model.
With a slogan that reads, "Being naked is the #1 most sustainable option. We're #2," you could deduce that Reformation is a brand that prides itself on its sustainability efforts. The brand hopes to achieve Climate Positivity this year, with a goal that includes sourcing 100% of its fabrics from either recycled, regenerative or renewable materials.
Reformation recently released a circular denim collection and is even working to develop vegan, plastic-free leather made from Mycelium (which is the root-like structure of a mushroom).
As a B Corp-certified brand, you can guarantee that With Nothing Underneath is prioritising the planet and is conscious about its environmental impact. The brand thrives on the ethos of buying less and buying better, offering a whole host of timeless wardrobe staples that are guaranteed to stay in your wardrobe for years to come. In terms of materials, the brand uses Organic Cotton, Tencel, recycled Silk and even its buttons are made from Corozo nuts.
Editor Verdict:
"There is, in my opinion, no shirt brand that compares to With Nothing Underneath. I own three of the brand's shirts and wear them season in, season out. Not only is the quality exceptional, but the fit is second to none—nailing that laid-back, casual vibe that still oozes luxury and expense. They're not wildly expensive in the grand scheme of things, but still more than your average £30 Zara buy. However, when I think about the cost per wear compared to high-street alternatives in my wardrobe, With Nothing Underneath comes out on top every single time." - Shannon Lawlor, Executive Beauty Editor
Arkitaip is focused on creating clothing that will last, with timeless designs and well-crafted construction. Created in Europe, Arkitaip utilises 100% Masters Of Linen-certified linen and can pinpoint where 95% of its raw materials originate.

Sézane has become one of the first-ever French brands to obtain a B Corp certification.

Editor Verdict:
"Nothing says French girl chic, quite like Sézane. The brand offers timeless staples that you will want to wear for years to come. After all, aside from manufacturing and fabrication, another true test of a sustainable wardrobe is ensuring you wear and re-wear your clothes again and again. Nothing is more sustainable than the clothes already in your wardrobe." - Zoe Anastasiou, Fashion Editor

As a B Corp-certified brand, you just know Aspiga takes its sustainability credentials very seriously. A few years ago, the label moved away from using new polyester in its products, choosing instead to use recycled polyester and other yarns made from recycled plastic such as EcoVero. Aspiga has also stopped using plastic in any of its packagings. Its clothing now comes in garment bags made from 100% cornstarch, which is compostable. The label also works with fair trade factories and repurposes all scrap fabric to create sustainable gift bags, scrunchies and face masks, thereby minimising waste.
The MARFA STANCE concept is based on buildable, adaptable, reversible and personalised clothing. Each piece can be worn in multiple ways and with multiple functions, promoting a buy less and buy better approach. Unique, buildable elements are available in each collection to evolve key styles, offering the ability to update and sustain your signature wardrobe season upon season.

The brand believes in quality over quantity and to slow things down they only present two collections per year. Production is kept as close to home as possible in order to keep transports shorter and in turn the CO2 footprint smaller. It works closely with a few quality factories in Portugal and Spain where shoe-making is a handcraft and good and ethical working conditions are a given. All plastic packaging has been removed, and the label works with premium leathers that are from Leather Working Group (LWG) audited members within Europe in order to ensure a supply chain of superior environmental performance.
Swim and resort wear brand, Boteh works with plant-derived fabrics or 100% cellulosic fabrics, as the brand describes. Their products are constructed from organic cotton, European flax linen and more. Cellulosic fabrics are not only more sustainable, but they also tend to be a more durable option.

Hunza G’s production process begins and ends locally in the UK, amidst a small group of individuals passionate about quality knit fabrics and considered swimwear construction.

These cool fashion staples are classic and timeless, and the quality of the clothing means that you'll have them for decades. The Scandi brand is the ultimate cool-girl uniform in London this season, but it's also the sustainable choice, becoming B Corp certified a few years ago." - Jenny Proudfoot, Features Editor
