7 Brands That Offer Eco-Friendly Clothes to Wear to Work

collage of five outfits from eco-friendly workwear brands

It’s been a couple of years since our last roundup of slow fashion workwear to try, so today we thought we’d share 7 brands that offer eco-friendly clothes to wear to work. These are all mainstream, easily accessible brands, most of which have inclusive sizing — not always the case with eco-friendly fashion and slow fashion!

Here’s a promising observation: I’ve written about slow fashion and eco-friendly brands for years, and companies’ policies and goals have come a long way since even the mid-2010s. The big brands that are committed to becoming more environmentally friendly are being more transparent and publishing more information online about their specific guidelines and metrics.

In the past, we’ve also talked about eco-friendly, zero-waste cleaning products, green cleaning products that actually work, and brands that offer safe beauty products. We also discussed where to recycle, donate, and sell your work clothes.

Readers, are you hunting for eco-friendly clothes to wear to work? Which are your favorite sustainable workwear brands?

7 Brands That Offer Eco-Friendly Clothes to Wear to Work


Reader-favorite brand Boden has some impressive goals for sustainability, including specific initiatives for each type of fabric they use, e.g., 100% sustainable viscose by 2025, 100% of cotton from mostly sustainable sources by 2023, and 100% Lenzing-verified Tencel Modal by 2025 (more details here).

They also try to make clothes that last — they offer a 365-day quality guarantee. 

Boden is part of the Better Cotton Initiative, which helps cotton growers use more sustainable farming methods (more than 80% of Boden clothing is made from cotton), and they strive for sustainable practices regarding their catalogs, packaging, warehouse, and offices.

Boden offers regular, petite, and tall sizes.


H&M is working toward only using recycled or other sustainably sourced materials by 2030 — they’re currently at 57%. The H&M Conscious line includes items made from at least 50% sustainably sourced materials, and many contain more. 

Other goals include becoming climate positive by 2040 (removing more greenhouse gases from the atmosphere than they contribute); using reusable, recyclable, or compostable plastic packaging by 2025 (they’ve already stopped using plastic shopping bags at stores); and using fossil-free commercial transport by 2050. They’re also reducing water and harmful chemical use at their suppliers.

You can read a lot more about H&M’s practices and goals on their Sustainability page.

Stores also have a recycling program: Bring any brand of unwanted clothing or textiles and you’ll get a coupon for 15% off. The clothing will be sold and reworn, reused (for non-clothing purposes), or recycled. 

H&M offers regular, petite, plus, and maternity sizes. 


Theory‘s newest fabrics are ethically sourced and developed with fabric mills that are involved in sustainable manufacturing. The company wants to reach 100% traceability in its supply chain (back to the raw materials) by 2025. 

We’ve mentioned the brand’s Good fabrics initiative in the past, but since then, Theory has added Good Cotton (in 2020) to its existing offerings of Good Wool (launched in 2017) and Good Linen (2019). Good Wool and Good Cotton are traceable, and all three are ethically grown. 

Theory is available at Nordstrom and elsewhere. 


Reformation classifies fabrics on a scale from A (“Allstars,” e.g., recycled cotton and Tencel Lyocell) to E (“Eww, never,” e.g., conventional cotton and conventional silk), based on their combined social and environmental impact. The company is committed to making up to 75% of their products with A & B fibers.

Reformation is currently carbon neutral but is aiming to be climate positive (i.e., removing more greenhouse gases from the atmosphere than they contribute) by 2025. Their production is already 100% water-neutral, and their California stores are Green Business Certified. 

You can read a lot more about their practices and goals by using their site’s Sustainability menu, and you can even buy climate credits (i.e., carbon offsets) on their website. 

Reformation is available at Nordstrom and elsewhere. In addition to regular sizes, they have a petites collection, an extended sizes collection that goes up to size 22, and a collection for customers with a full C to DD cup size. (Note: Some of Reformation’s pieces aren’t suitable for more formal dress codes; much of it would be appropriate for casual, business casual, or creative workplaces.)

Eileen Fisher 

Eileen Fisher has a three-part social consciousness focus that includes Sustainability. They’re committed to using organic, recycled, and sustainable fibers; using factories with certified dye processes; increasing water efficiency in their manufacturing; and more. In 2017, they stated they would reduce their absolute scope 1 and 2 greenhouse gas emissions by 100% by 2025 and certain absolute scope 3 emissions by 25% by 2025. (These are the three scopes, in case you’re interested.) 

For several years, the company has been buying renewable energy credits to support wind power for 100% of the electrical consumption in its stores and corporate offices. 

You can read about their “Horizon 2030” plan on their website.

Also, with their RENEW program, you can bring in your “worn or torn” Eileen Fisher items in exchange for a $5 Rewards Card.

Eileen Fisher is available at Nordstrom and elsewhere (and their popular stretch crepe pants are in our Workwear Hall of Fame). They offer regular, petite, and plus sizes. 

Karen Kane 

Karen Kane‘s five core values are listed on its website: Be Transparent, Be Ethical, Be Compassionate, Be Conscious, and Be Sustainable. In 2020, the company became a Certified B Corp.  

The brand is increasing the percentage of recycled and sustainably sourced textiles in its production and has made other changes, such as using more eco-friendly packaging, recycling more and using less water and power in its manufacturing, and switching from using new hangers to reused hangers (which are then recycled).  

To reduce the company’s greenhouse gas emissions, they’ve ensured that 35% of the total energy use at their California manufacturing facility comes from renewable resources (and they have plans to increase it).

Karen Kane is available at Nordstrom, Amazon, and elsewhere, and they offer regular, petite, and plus sizes. 

Ted Baker

Ted Baker London features their sustainable pieces in their Conscious Shop. These women’s styles contain more than 50% responsibly sourced materials, e.g., recycled polyester, organic cotton, and other fabrics.

A few of the company’s goals are to solely use organic, recycled, or Better Cotton Initiative cotton by 2024; to only use responsibly sourced materials by 2030; and to only use regenerated cellulosics (i.e., plant-based materials such as viscose, lyocell, and modal) from FSC or PEFC Certified forests, with a further 50% produced through sustainable production methods by 2025.

You can learn more about the company’s efforts on its Sustainability page, but it’s not completely up to date; e.g., as of early 2021, one section noted, “A supply chain map will be ready for early 2020.”

Ted Baker also avoids certain materials for animal welfare reasons, including angora, mohair, and fur (they do sell faux fur) — and they are phasing out down and feathers. (Fun fact: The company maintains beehives on the roof of its headquarters.)

Ted Baker is available at Nordstrom and elsewhere.
