Sustainable fashion is a growing market trend as we learn more about how our shopping habits adversely impact the environment. We're here to share the top sustainable fashion brands worth noting, all of which have earned the coveted green halo among consumers for their 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 through washing our clothes microplastics enter our oceans. 

Amid grave and dire circumstances, it can be quite overwhelming to take action. Buying less, shopping second-hand, investing in better quality pieces, keeping clothes longer, recycling, repairing and clothes swapping are all ways we can help lesson our fashion footprint. But another really big one is shop sustainable fashion. There are many noteworthy brands that are doing their bit and making a stand for sustainable fashion; and with Earth Day approaching, now is a great time to do your part.

Satisfy your fashion fix with our pick of the best sustainable fashion brands, including big high street names and more niche brands. From vegan leather boots to ethically-sourced shoes, you'll quickly find eco-friendly buys for every season. 

What makes a fashion brand sustainable?

Sustainable fashion is either largely undefined or defined, but encompasses many variations that exacerbate the confusion. Within the greater ecosystem, sustainable fashion is a new approach to sourcing, manufacturing, and designing garments, and focuses on reducing carbon footprint and environmental impact. The concept, rooted in tenets of ethical practices, naturally overlaps with social justice causes, like labor rights, women's empowerment, etc. behind the scenes. 

But in the age of greenwashing and misinformation, what makes a fashion brand sustainable? To start, sustainable fashion brands aim to combat lax regulations and other commonplace issues within the fast fashion industry. These issues include: complicated supply chains, high consumption rates, chemical pollution, water and textile waste, and grisly human rights violations. In response, there are several criteria, qualifications, and standards that brands must uphold. All in all, sustainable fashion brands are characterized by their actions, not their promises.

  • Sustainable fashion brands ethically source ingredients, whether it's through localization or other vehicles.
  • Sustainable fashion brands endorse supply chain transparency. Generally, a brand with supply chain transparency makes products in their base country, or in developed nations where workplace health and safety codes are strictly followed and workers are paid living wages. The product lines tend to be smaller for greater control over the process, and typically come out of smaller factories rather than behemoth workshops.
  • Sustainable fashion brands have ethical business practices and adhere to basic human rights laws. Try to shop Fair Trade certified companies whenever possible. The term "fair trade" defines when employees in developing countries are paid fair and equitable prices for their work by companies in developed countries.
  • Unlike fast fashion brands, sustainable fashion brands leverage durable and enduring materials in their production process. Every design can be recycled, worn multiple times, has a renewable energy component, and reduces waste (carbon, water, you name it). When possible, look for handmade items, zero waste packaging, and carbon neutral shipping services.
  • Sustainable fashion brands take greater social responsibility. They typically promote give-back programs that aligns with their ethos, values, and mission to help others.

The Best Sustainable Fashion Brands To Shop


Sustainable fashion ASICS New Shoe Collection

Various styles, sizes, and variations available across footwear and activewear

Meet the Earth Day Pack: a new eco-conscious collection launched by ASICS. The pack features brand heroes across ASICS running and Sportstyle ranges, including including GEL-NIMBUS™ 23, GLIDERIDE™ 2, and GEL-LYTETM™ III shoes, plus clothing. Each product included in the collection features a bright sunflower icon on its page.

As an advancement of the brand's sustainable initiatives, this capsule uses approximately five tons of recycled textile waste as part of a series of energy-efficient production processes. (That's the equivalent of 25,000 t-shirts recycled into new shoes.) The inner part of each shoe was developed through solution dyeing. Compared to conventional dyeing processes, this approach reduces CO2 emissions and water waste by a large percentage.

Sustainable Fashion Levi's Jeans

Sizes available: US 23-32 | Styles available: 11 | Lengths available: 26 and 28

When you think of denim and the best jeans, you automatically think of Levi's: the market leader of quality apparel at affordable prices. Levi's presents many of the best skinny jeans, slimming jeans, boyfriend jeans and mom jeans on the market to date.

But the brand transcends denim: Levi's is at the forefront of sustainable fashion, with planet-friendly collections including WellThread™. The brand strives to use recycled plastics, reduce landfill waste, and shrink its carbon footprint. Additionally, 50% of Levi's products are now made with the brand's Water Less techniques, with more than 1.8 billion liters of water saved and 129 million liters recycled. Levi's also unveiled a secondhand storefront with resale designs.

From the Levi's Premium Collection, the Wedgie Straight Jeans features eco-friendly materials and unique details for a better fit. This pair features belt loops, a cropped inseam, contrast stitching, copper- and silver-tone hardware, belt loops. Sustainable fashion has never looked better.

If you’re looking to create an eco-friendly capsule wardrobe, Everlane is your answer. The US brand prides itself on its entirely transparent supply chain, partnering with the best ethical factories around the world. They aim to use recycled materials, address water use and chemical inputs, and invest in carbon-offset projects. 

Of all the offerings, we love The Tread Runner, the brand's ultimate running sneaker. With The Tread, Everlane aims to create "the world's lowest-impact sneakers" that are proudly carbon neutral. As an extension of this mission, the brand leverages full-grain leather and has reduced the amount of virgin plastic used in its supply chain.

Drawing inspiration from retro '80s track shoes, this iteration integrates eco-friendly and durable materials for comfortable wear — such as leather paneling, a cushioned insole, and a contrasting tread outsole. Since they're considerably nostalgic, you'll want to pair these shoes with grunge-esque mom jean outfits.

More importantly, the pair is designed from sustainably sourced materials, including a low-plastic sole and 100% recycled polyester lining. The laces and linings are made of recycled plastic bottles (In fact, 9.5 bottles are renewed to make every pair). It embodies sustainable fashion, signaling a better, more reformed industry in the years to come.

Sustainable Fashion Patagonia Coat

Sizes available: US XXS-XXL | Styles available: 10

Patagonia is no longer coined as the brand for Wallstreet bros and their fondness for vests, also known as the "Midtown Uniform". Rather, the brand has evolved into a sustainable fashion icon, with the climate crisis driving its manufacturing practices, supply chain, and marketing. Patagonia aims to reduce carbon emissions and prioritizes efficient use of resources: Waste gets upcycled into new products that get reused multiple times. To meet these goals, the brand has spearheaded numerous programs, including Worn Wear: an initiative enabling customers to shop for used items in select stores.

The best-selling Better Sweater Fleece Jacket is a testament of Patagonia's steadfast efforts. Each fleece is made of 100% recycled polyester and dyed with a low-impact process. Compared to traditional dyeing methods, the Patagonia approach is more energy efficient, reducing the use of dyestuffs, energy and water. Additionally, this fleece is fair traded certified sewn. 

We also love Patagonia's Women's Down With It Jacket, which is much better alternative to faux fur coats.

Sustainable Fashion 101: How to shop ethically

  • Shop staple pieces: While on-trend garments are considerably snazzy, they're often limited to one-time-occasion wear. You're more likely to discard your item faster than you purchased it. Instead, invest in the classics: evergreen outfits that'll last you through the seasons and never depart from the fashion cycle. Though generally more expensive, they tend to be made of durable, eco-friendly, and soft materials, which won't wear overtime. This brings us to the next point, below.
  • Transform your shopping behavior: To build an sustainable fashion wardrobe from scratch, you must change your approach to shopping. If an item is super cheap, chances are it's way too good to be true; and it's most likely a biproduct of the fast fashion industry. Aside from assessing a garment's chic factor and price, you'll want to analyze its carbon footprint and energy used to make it. Also, try thrifting — there are many secondhand stores to explore. Either way, you'll want to think quality over quantity.
  • Do your research: When it comes to sustainable fashion, the standards are always influx and changing. That's why it's imperative to be informed. Do your homework and know where to shop. Understand the latest ethical labels and their manufacturing processes; and examine the materials used. Ask the right questions if you're uncertain, and do the nitty-gritty work in searching for answers. Ignorance is not bliss.
  • Donate your unwanted clothes: Before tossing your outdated 'fits into a landfill, consider donating them to a good cause. This effort is not only sustainable, it's philanthropic, too. It always feels great to give back.
  • Tailor your clothes: So maybe you don't want to donate or discard your garment; however, its quality has visibly diminished. Fortunately, there are ways to repair your clothing in a jiffy — whether you take matters into your own hands or pay a professional. This measure goes a long way in contributing to the sustainable fashion movement.
  • Think Fair Trade: Fair trade practices ensure safer working conditions for employees and uphold rigorous standards. More evidently, the fair trade complex fosters greater ecological integrity, social justice, and active change to the fashion system. Many brands are fair trade certified, including Patagonia.
