Sustainable and ethical fashion continues to dominate the industry conversation, but greenwashing remains a very real problem. Brands and consumers alike have woken up to the environmental and human cost of fast fashion, and genuinely ethical labels are now easier to find than ever. That said, not every brand claiming the ethical badge truly earns it.
Ethical brands do more than cut their carbon footprint. They also address the human cost of the clothes we wear: fair living wages, safe working conditions, and transparency across the supply chain. These are standards that many garment workers still do not benefit from, and they matter just as much as the materials a brand chooses to use. Sustainable fashion, at its best, reduces a brand’s impact on both people and the planet while still producing clothes we genuinely want to wear and keep for years.
To help you find the brands actually doing this well, we have pulled together some of our favourites below.
Reformation
Established in Los Angeles in 2009, Reformation has built one of the most credible sustainability reputations in fashion. The brand began by retailoring vintage clothing, and that founding philosophy of keeping clothes in circulation has stayed central to everything it does. Today, Reformation publishes a quarterly sustainability report, holds Climate Neutral certification from The Change Climate Project, and has set near-term targets to reduce its carbon intensity and transition fully to recycled, regenerative or renewable materials.
On the people side, Reformation works with the Fair Labor Association to uphold strong labour standards across its supply chain, and its Los Angeles factory operates to the same rigorous expectations as its partner factories around the world. Crucially, the brand does not shy away from admitting where it still has work to do, which is precisely what gives its sustainability claims genuine credibility. With a 2025 sustainability report already published, Reformation continues to set the pace for what honest, progress-led fashion looks like.
Girlfriend Collective
Girlfriend Collective builds its activewear from post-consumer recycled materials, primarily plastic bottles and fishing nets that would otherwise end up in landfill or ocean. Each product page lists exactly how many recycled bottles went into making the item, and the brand uses OEKO-TEX certified, eco-friendly dyes throughout. The packaging is 100% recycled and recyclable, down to the hangtags. Good On You rates the brand as “Good” across both its environmental and people criteria.
What sets Girlfriend Collective apart, however, is its transparency about the things it has not yet solved. The brand openly acknowledges that synthetic fabrics release microplastics when washed and actively sells washing bags to help customers mitigate this. It also runs a ReGirlfriend take-back programme, converting old garments into new ones, and a peer-to-peer resale platform to extend the life of its pieces further. That combination of honesty and practical action is rare, and it makes Girlfriend Collective one of the more trustworthy names in sustainable activewear.
Stella McCartney
Environmentalism has always been central to Stella McCartney’s brand identity. As a fully vegan label, Stella McCartney refuses to use leather, fur, or exotic animal skins, and that commitment extends to its collaborations, including its long-running partnership with Adidas on sustainable sportswear. The brand measures its environmental impact against standards set by the International Labour Organisation and publishes the results, giving consumers a clear picture of where it stands rather than simply where it aspires to be.
In addition to its material choices, Stella McCartney uses regenerative and recycled fabrics wherever possible and actively invests in next-generation textile innovation. For a luxury label operating at this price point, its refusal to treat sustainability as a marketing add-on sets it apart from many of its peers. It remains one of the few high-fashion brands where the ethics and the design genuinely feel like one and the same thing.
H&M Conscious Choice
H&M’s Conscious Choice line demonstrates that more sustainable options do not have to come with a luxury price tag. Each piece in the collection contains at least 50% more sustainable materials than H&M’s standard range, including organic cotton and recycled polyester, and the brand has a broader goal of making all its products from recycled or sustainably sourced materials by 2030. Currently, around 80% of the materials H&M uses already meet that standard.
It is worth noting that H&M has faced scrutiny over its sustainability claims in recent years. Critics argue that recycled polyester still sheds microplastics and that the Conscious Choice threshold is a relatively low bar. H&M also requires suppliers to sign a Sustainability Commitment covering fair wages and safe working conditions, though independent verification of those commitments remains patchy. On balance, Conscious Choice represents a meaningful step in the right direction for a brand operating at H&M’s scale, but it rewards a critical eye. Look for pieces with the highest proportion of certified sustainable materials and treat it as a complement to, rather than a replacement for, shopping with more fully committed ethical brands.
Boden
Boden takes a quietly serious approach to sustainability. The British brand is transparent about its global supply chain, conducts regular supplier audits, and uses organic cotton, recycled polyester and Tencel across its collections. Its packaging is now 100% recycled cardboard and recyclable bags, and the brand reported achieving carbon neutrality for Scope 1 and 2 emissions in 2022.
Beyond the environmental side, Boden’s commitment to quality is itself a sustainability argument. Clothes built to last, with consistent sizing and a focus on timeless design, are far less likely to end up discarded after a season. The brand also supports clothing recycling through charity partnerships and offers repair services to help customers get more life out of their garments. For everyday wear that combines longevity with responsible sourcing, Boden remains one of the more dependable choices on the British high street.
Eileen Fisher
“Circular by design” is not just a tagline for Eileen Fisher. The brand actively collects worn Eileen Fisher garments, resells those in good condition, and repurposes anything too damaged to go back on a rail. That take-back programme, known as Renew, has diverted millions of garments from landfill since it launched and represents one of the most genuinely circular models in mainstream fashion.
In terms of materials, 98% of Eileen Fisher’s linen is organic, and the brand draws heavily on recycled and sustainably sourced fabrics throughout its collections. The aesthetic is understated and built for longevity rather than trend, which reinforces the sustainability argument further. Consequently, Eileen Fisher tends to attract customers who want fewer, better things and are willing to invest accordingly.
Cuyana
Cuyana built its brand around the idea of “fewer, better things,” and its sustainability credentials follow that same logic. The brand invests heavily in its supplier relationships, prioritising heritage craftsmanship and long-term partnerships over the cheapest available option. As a result, Cuyana traces its supply chain closely and works directly with the artisans and factories producing its pieces.
In terms of materials, Cuyana is working towards having 100% of its products made from sustainable fabrics, including recycled and upcycled options. The brand also runs a resale service and donates through charity partnerships, reinforcing a circular approach that goes beyond simply choosing better raw materials. For shoppers who want quality investment pieces with strong ethical foundations, Cuyana is one of the most coherent options available.
