The best sustainable clothing brands prove great style doesn't need to cost the environment. As we become increasingly aware of the detrimental impact modern fast-fashion shopping habits have on the environment, the demand for brands that put the planet before profit is growing. Shopping sustainably is easier than ever, thanks to a host of exemplar brands leading the way with ethical mindsets and sustainable initiatives.

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 causing 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.

Why is it important to shop sustainably?

Have you ever thought about how your best jeans might impact the environment? They might be part of your capsule wardrobe, 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 fibre 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 selling clothes online, and borrowing pieces using the best dress rental services are all ways we can help lesson our fashion footprint. But another really big step is to shop from environmentally friendly clothes brands that are actively operating in a better way.

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, Thought Clothing, 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.

“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.
