By their very definition, sustainability and fashion are inherently at odds with one another. The fashion industry thrives through consumption, with each season putting forward a new trend du jour for consumers to buy and just as easily dispose of.

In fact, the clothing space is the third biggest polluter behind food and construction, and responsible for 10 per cent of global carbon emissions – more than shipping and aviation combined. Fashion’s buisiness model relies on keeping prices low, with the large-scale processing of materials creating chemical waste that’s often dumped in water, while cheaper alternatives to synthetic materials are causing widespread microplastic pollution.

And then there’s fast fashion, where clothes manufactured from cotton leads to over-abstraction of water in countries like India and China that are already threatened by droughts from climate change. The human cost is just as dire. Labour exploitation, unsafe working environments and wages not fit to live on are all rife in the fashion industry which has trebled in size in the last few decades. 60 million people are estimated to be working globally, many still in sweatshops.

But it’s not all doom and gloom. The fashion industry is constantly evolving with exciting new designers, slow-fashion labels and innovative production lines that are all helping to clean up fashion’s footprint.

While labels like & Daughter and Herd are restructuring the wool production line, brands including E.L.V Denim and Nudie Jeans are a go-to for organic and recycled denim jeans. For eco-friendly, everyday staples, A-lister favourites Everlane, Ganni and Reformation use low-impact materials, while luxury labels like Stella McCartney and Vivienne Westwood were early adopters of innovative fabrics. Helping you tread more lightly on the planet, shoe brands Veja and Humans are Vain are proving vegan alternatives can look just like the real deal, too.

Above all, sustainability when it comes to fashion is mainly a mindset. Whether it’s shopping second hand via Vinted or Depop, frequenting your local charity shops, embracing the rental market or making considered purchases from eco-friendly labels, it’s up to you to create a greener wardrobe.

While it may seem there’s more choice than ever, the amount of greenwashing can throw some confusion in the mix. So, we’ve rounded up all our favourite sustainable clothing brands below, from vegan trainer labels to trend-led high street brands.

A good pair of denim jeans can prop up your wardrobe for years to come. Swedish brand Nudie Jeans only uses certified organic and fairtrade recycled cotton for its denim offering. This means the brand reduces their enviromental impact from the very first step in making a pair of jeans, as organic cotton is grown without artificial fertilizers, pesticides or hazardous chemicals. Both of its suppliers in Turkey and India are Fairtrade certified, guaranteeing fair working conditions and the correct payment to farmers. As for the collection, expect classic jean silhouettes and length options, as well as retro-inspired skirts, dresses and shirts.

One of the most affordable places to shop more sustainable fashion, Nobody’s Child favours reduced-impact alternatives. From organic cotton and TENCEL lyocell (derived from certified responsible forestry) to ECONYL regenerated polyamide and REPREVE recycled polyester (sourced from pre-and post-consumer synthetic materials like bottles and fishing nets), the label is also transparent about its tier 1 suppliers. While it doesn’t solely use eco-friendly materials, all its fabrics are at least 75 per cent reduced-impact alternatives. Head here for everyday dresses, wedding guest attire and dopamine-including prints and colours.
