Shop with the brands doing their bit to build a better tomorrow.
If you’re searching the Internet for sustainable clothing brands, chances are, you’re keen to cut down your fast fashion consumption and make your wardrobe a little more eco-friendsly.
Shopping ethically is a great way to reduce your carbon footprint and overall emissions, especially now more and more brands are focusing on producing fewer, better quality and season-less clothes – clothes that customers won’t grow tired of.
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. Here’s a guide to help you.
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 fall into three categories – social, environmental and commercial. They specifically tackling 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
But alongside this, sustainable fashion brands will also consider how they source their 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.
So how can you spot if a brand is genuine in its sustainability efforts? Dai explains:
- 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 repair 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.”

Reformation
As a major step in their ambitious plan to achieve Climate Positivity by 2025, the brand is introducing a new platform of wardrobe staples that are made to be remade, beginning with Circular Denim.
The fashion industry operates on an endless make-sell-pollute cycle, with roughly 90% of clothing discarded before the end of its lifetime. Ref’s new Denim collection is made from fabric scraps that could’ve been trash but through collaborating with leaders of denim innovation Strom and Bossa, they've created a line of fully Circular Denim. Ref are thrilled to bring their technology to Ref's best-selling denim and to also push the fashion industry towards a better, more transparent shared future at the same time.
With Ref, Strom and Bossa prep the denim scraps and combine them with FibreTrace and organic cotton, they are then woven into denim that ultimately becomes a pair of jeans. These fabrics are made from 20% Recycled Scrap Cotton and 80% FibreTrace Cotton (a technology enabled fiber that allows consumers to follow denim’s entire lifecycle—from fiber, to product, to finished product).
