The best sustainable clothing brands - how to shop stylish fashion with a conscience

Little by little, sustainable jewellery, ethical jewellery

The best sustainable clothing brands prove great style doesn't need to cost the environment. As we become increasingly aware of the detrimental impact fast fashion shopping habits have on the world we live in, the demand for brands that put the planet before profit is growing. 

It's now easier to shop more sustainably than ever as the industry rapidly grows due to consumer demand. While sustainable clothing used to carry a hefty price tag, it's becoming increasingly more price-accessible. Whether you're looking for luxe t-shirts, jeans, or even footwear all can now be updated with slow fashion and sustainable alternatives.

It's no secret that the fashion ecosystem has contributed to the ever-growing climate crisis while compounding existing environmental, labor, and social injustices. The fashion industry produces 10% of humanity’s carbon emissions, emitting more than international flights and maritime shipping combined. Not only this, fashion production is the second-largest consumer of the world’s water supply, and washing synthetic fibers causes microplastics to enter our oceans and harm marine life. 

“Sustainability in the fashion industry is not just important, it's vital," says Charlie Bradley Ross, Founder & Director of Offset Warehouse & The Sustainable Fashion Collective. That's why we always turn to the best sustainable clothing brands when shopping for new pieces to add to our closet.

The best sustainable clothing brands as chosen by our fashion team

“With systemic change, the fashion industry can lift millions of people out of poverty, providing them with decent and dignified livelihoods. It can preserve and restore our living planet. Fashion can be a powerful force for good - bringing people together as a source of joy, creativity, and expression.” says Bradley Ross. From up-and-coming labels to well-loved names, these are the very best sustainable clothing brands to shop now.

17. Veja

Best sustainable clothing brand for cult trainers

Sizes: 35-48 | RRP from: $142 / £105

Transparent supply chain 
Vegan styles available 
Super on-trend

Beloved by the Princess of Wales French footwear brand Veja has reached cult status thanks to its signature sneakers that hit high on sustainability and style factor. And as it is an ethical brand too, you can have no guilt when indulging.

From material to supply chain, every element of a Veja sneaker is done with the planet's well-being in mind. For example, the rubber soles used for each design are bought at twice the market price to help protect the Amazon rainforest, which is where the material is derived from. Recycled plastic bottles, cotton and polyester are used to create uppers, and innovative leather alternatives are used in the brand's vegan range. 

Why is it important to shop sustainably?

Have you ever thought about how your jeans might impact the environment? They might be an essential, but denim is one of the planet’s worst offenders using an average of 1,800 gallons of water per individual pair thanks to the thirsty raw cotton material, not to mention the synthetic chemical-laden dyes. 

“For years, manufacturers have been producing fabrics and garments irresponsibly: disposing of carcinogenic chemicals, toxic fertilizers, pesticides, and dyes into the rivers and the earth," says Bradley Ross.

“The raw materials and resources we use far supersede the rate at which we can replace them. To put it into context, by 2025, 1.8 million people will be facing absolute water scarcity. Coupled with the devastating environmental effects of irresponsible fiber production, we're talking about the destruction of biodiversity and ecosystems affecting millions of animals and people worldwide.”

Amid dire circumstances, it can seem overwhelming to take action. Investing in better quality clothes that last longer, shopping second-hand pieces via the best online vintage stores, repairing old clothes or recycling by learning how to sell clothes online, and borrowing pieces using dress rental services are all ways we can help lessen our fashion footprint. But another really big step is to shop from environmentally friendly clothes brands that are actively operating in a better way.

Luckily this has also become a high-priority issue for some of our favorite mainstream fashion brands too, with many looking at their own carbon footprint, particularly jeans production.

What makes a fashion brand sustainable?

When it comes to clothing brands, 'sustainable' is often used as an umbrella term that encompasses several aspects. However, broadly speaking, it means approaching design, fabrics, sourcing, manufacturing, and packaging in a way that doesn't harm the environment.

This often also goes hand in hand with ethical practices which encompass social justice, like labor rights, women’s empowerment, fair wages, and working conditions. If a brand is considered sustainable, its values will often naturally overlap with ethical practices.

“A sustainable or responsible brand seeks to minimize its negative environmental and social impact. Every aspect of the supply chain from raw material, to shop floor, to how the garment is cared for once in the customer's hands can be considered," explains Bradley Ross.

Which fashion brands are sustainable? 

The past few years have seen a surge in stylish brands making strides in protecting the planet, including independent labels and slow-fashion retailers such as Everlane, Omnes, and Reformation. 

Brands aren't always honest with their efforts, though, and greenwashing - a term used to describe the marketing spin a brand may use to convey misleading environmentally friendly claims - can often deceive customers into believing it is an ethical and sustainable business. When in reality, it may not be. 

Authentically sustainable brands will have information about their methods and practices on their websites and offer clear insights into the actions they are taking to produce in a responsible way. Look for brands that do the following:

  • Use ethically sourced raw materials or upcycle waste and deadstock fabrics.
  • Employ energy-saving manufacturing techniques and either have zero carbon emissions or offset them. 
  • Endorse supply chain transparency by telling you where garments are made and who made them.
  • Have ethical business practices and adhere to basic human rights laws. Look for the Fair Trade certification which means farmers and workers have safe working conditions and are paid fairly. 
  • Focus on timeless designs that will last, rather than trendy styles that will date. 
  • Use zero waste packaging. 
  • Encourage consumers to recycle well-loved pieces with in-house recycling facilities. 
  • Take social responsibility, promoting charities and programs that aligns with their ethos, values, and mission to help others.
