Sustainable clothing is gaining traction to combat the world of fast fashion. The fashion industry is responsible for almost 10% of global emissions and is on pace to double by 2030. Americans toss an estimated 11.3 million tons of textile waste, or 2,150 pieces of clothing per second, into landfills every year. Studies have found that on average, clothes are discarded after only 7-10 uses.
Fashion culture encourages us to quickly move on to the latest styles and to forever keep cycling through a new wardrobe. And I’m not immune. I love shopping and getting new things, and have succumbed to retail therapy more than I’d like to admit. Join me in slowing down purchasing and move toward adding sustainable clothing to our closets, while keeping old, worn items out of the landfill.
For an in depth look at fashion waste, I recommend this Bloomberg article.
How to minimize your fashion environmental impact
Buy less
Curbing your purchases is BY FAR the most impactful step in reducing your style footprint. Stop and assess whether a new item is really needed. I totally get retail therapy and have done my fair share in the past, but if you take time to stop and honestly evaluate purchases, you will probably find that in reality, you actually don’t need another t-shirt, pair of shoes, or a new purse. Train yourself to be more selective in your purchases.
We are probably all guilty of buying clothes simply because it was too good of a deal to pass up. Or maybe we bought an item with the intention of fitting into it soon, only to have it sit and gather dust in the closet.
I think there’s value in taking a Marie Kondo approach to shopping: Does this item bring you joy? OK, maybe joy is a little much, but do you like how you feel in the clothing? And not only comfort, but does it affect your confidence? Do you love it? Do you love it enough to be really disappointed if they didn’t have any in your size? If there’s any waffling or doubt at all, walk away.
Consider renting clothing that is only needed for a short time. Everyone knows you can rent a tuxedo, but did you know you can rent all types of apparel, too? For formal dresses and gowns, check bridal shops, or search for local businesses that rent dresses. You can also rent maternity clothes, outfits for vacation, or just regular casual clothes from businesses like Rent the Runway.
Make smart clothing purchases
Go for quality over quantity. I’ve always been a firm believer in this approach. I would rather spend more upfront for a well-made article of clothing than one cheaply-made from poor quality materials. You know the ones that morph into a non-human shape, shrink, pill, or just look plain terrible after only a few times through the laundry. Invest in well-made classic pieces that will never go out of style and that can be used for a variety of occasions.
Avoid shopping at notoriously bad fast fashion stores like Shein or Forever 21. These mass clothing producers care nothing for excess, the use of toxic chemicals, or the exploitation of workers. Take time to educate your kids about these issues. I sat my teenage daughter down and explained to her why we won’t be buying clothes from these sweatshops, and she agreed that we should abstain from those options. Research clothing companies and do your best to buy from ethical businesses.
Shop thrift and vintage clothing
Purchasing vintage and thrift clothing extend garment lifecycles, thereby reducing waste and the demand for new production, which in turn lowers resource use, energy consumption, and environmental pollution, making this arguably the most eco-friendly way to shop. And as an added bonus, this is usually a much less expensive way to shop.
Check out your local second-hand stores or shop online at outlets like Vestiaire, thredUP, or Poshmark.
Avoid synthetic fibers
Almost 70% of today’s clothing is composed of synthetic materials, the majority of that being polyester. Other common synthetic fabrics include spandex, nylon, and acrylic. These materials are all derived from fossil fuels, and their production uses more energy and produces more emissions than the processing of natural fibers.
In general, synthetic fibers require more harsh and potentially toxic chemicals in the production than natural fibers.
Because they contain plastic, synthetic materials are not biodegradable and can take centuries to decompose, leaching chemicals into the soil and water in the process.
Synthetic fabrics significantly contribute to the world’s microplastic problem: it is estimated that up to 35% of microplastics in the ocean and 71% of microplastics in rivers come from synthetic clothing. In your own home, textile microplastics compose 33% of dust floating around. Read more about plastics here.
Besides environmental impacts, synthetic fabric can stink in other ways. Literally. Polyester attracts more oil from your skin, requiring more frequent laundering. In fact, one study showed that polyester fibers can absorb odor-causing compounds and not wash out completely, leading to a buildup of odors over time. That explains why I’ve noticed some of my workout wear still smells funky even after washing—glad it’s not just me!
Instead of synthetic fibers, select clothing made from natural, biodegradable, sustainably sourced materials, such as organic cotton, hemp, linen, bamboo, wool, silk, cashmere, or Tencel (aka Lyocell and Modal). Clothing made from recycled materials is generally a good option.

Choose non-toxic clothing
Adding color to fabrics is a very water-intensive process, responsible for 20% of global wastewater. In addition, toxic chemicals are often used, which find their way to both waterways and our skin. According to a scientific review on ecotoxicological and health concerns of textile dyes, “Textile wastewater has been found to contain a wide range of toxic dyes, heavy metals, such as mercury, chromium, cadmium, lead, and arsenic which are required in the production of textile dye color pigments, as well as aromatic compounds.” Of these substances, some are toxic, known carcinogens, and/or have mutagenic (DNA-altering) properties for both aquatic life as well as humans.
Finishing processes also utilize a large number of harmful chemicals. Perhaps the chemicals of most concern are the Per- and polyfluoroalkyl substances (PFAS), such as Perfluorooctanoic acid (PFOA), Perfluorooctane sulfonate (PFOS). PFAS resist grease, oil, water, and heat, which is useful in many applications but do not degrade in the environment, thereby being dubbed as “forever chemicals.” They enter the food chain, ultimately reaching us; most people in the United States have detectable levels of PFAS in their blood. These are associated with numerous serious health effects.
PFAS is most commonly found in performance fabrics, which are labeled as stain or wrinkle resistant, waterproof or water-resistant, flame resistant, or antibacterial or antifungal, have undergone processing with chemicals to achieve these characteristics.
You can protect yourself from harmful chemicals by choosing clothing that is bluesign or OEKO-TEX certified. There are safer alternatives to PFAS, but that will likely require some research on your part. Check for specific chemical names, azo-free dyes, PFC-Free or PFAS-Free labels, product information about the technology used, company sustainability information, or contact customer service and ask.
Alden Wicker of EcoCult highlights 17 Cheap Non-Toxic Fashion Brands You Can Find at the Mall on her website. She is also the author of To Dye For, a well-researched book detailing use of toxic chemicals by the fashion industry. If you are interested in learning more about this subject, I highly recommend this fascinating and sobering read.
Buy ethically made clothing
The fashion industry employs around 60 million people worldwide. About 80% are women of color, an already marginalized population. Asia is the global center for textile production, with China leading in textile exports. India and Bangladesh are other major textile hubs. Environmental regulations in these countries are poor, and enforcement of labor laws, if they exist, is pitiful.
Sadly, unethical treatment of textile workers is nothing new, and runs rampant even today, with fast fashion at the core. These companies prioritize speedy, inexpensive, mass production of clothing to keep up with the latest fashion trends and are largely responsible for clothing production doubling over the last 15 years.
Workers face poverty level wages with 14-16 hour workdays, 6-7 days per week, with mandatory overtime (which often goes unpaid). They face sexual harassment or assault, verbal or physical abuse, retaliation for union workers, or being forbidden from taking breaks. Women may be denied maternity leave, or fired just for being pregnant.
Unsafe working conditions are another threat. There’s no workers comp. You get hurt on the job, you are left without an income. All those toxic chemicals discussed earlier? Garment workers are exposed to those in very high amounts, in addition to extreme temperatures and unstable or otherwise unsafe buildings. Add in child laborers to these awful conditions.
And finally, modern slavery and debt bondage are other commonplace among all stages of the growing, harvesting, or manufacturing processes.
Look for clothing made by companies with transparent sourcing and manufaturing information, as well as certifications such as Certified B Corp, Fair Trade, or Fair for Life.
Properly care for your sustainable clothing
- Read care labels for clothing and follow care instructions to prolong the quality and life of your clothing.
- Don’t automatically toss worn clothing in the hamper. Consider how long the item was worn (synthetic fabrics needs to washed more frequently) and if not visibly dirty or stained and passes the old sniff test, maybe it can stand another wear.
- Find a good tailor or seamstress (unless you know how to sew) to repair your clothing to give it more life.
- Check out these additional clothing care tips from H&M and Nordstrom to help make your clothing last longer.

Activewear can be especially tough to find in natural fibers. Tencel modal or lyocell are great options. There are quite a few sustainable companies with sustainable yoga clothing and other workout wear. I am a big Athleta fan, or more accurately, an addict. Many of their products are made with natural fibers, and these can by found by filtering fabric material. Other great options include Girlfriend Collective, Vuori, Patagonia, and Nordstrom brand Zella.
- Athleta – Certified B Corp, Fair Trade certified. Shop earth-conscious products that are made with at least 30% organic cotton, Tencel, or recycled nylon/polyester.

Sustainable underwear
Look for underwear made from 100% organic cotton or other natural fibers. Besides being biodegradable and eco-friendly, these fabrics are more gentle on skin, breathable, and absorbent than synthetic fabrics, which trap heat and moisture. This can increase odor and create a perfect breeding ground for yeast infections.
Natural fabrics are also less likely to contain toxic chemicals, which nobody wants in the vicinity of their…business.

Use a reusable lint remover
Skip the tape lint roller and go for a reusable tool like the Chom Chom Roller Pet Hair Remover/Reusable Lint Roller or Beautural Pet Hair Remover to get lint and pet hair/fur off both clothing and furniture.
Plastic-free lint removers include:
- Redecker lint brush – beechwood handle with natural rubber bristles
- Ruri’s Portable Lint Remover – copper head and beechwood handle
- Fur-Zoff Pet Hair Removal Tool – made from recycled glass
Clothing donation options
For many, the default method of getting rid of unwanted clothing is donation. While this is good in theory, whether your clothes actually are given to someone in need or sold in a thrift store is a question you need to ask. Much of what is donated is actually thrown away or shipped overseas.
The best choice is to start with someone you know. Maybe you have a friend or family member that could use some of your unwanted clothing.
Next, try a local Buy Nothing or Freecycle group. I have come to really like this option for donating items because I know they’re going to actual people that want them, rather than some mystery destination, like the landfill.

If donating is your preference, by all means, continue to donate, because there are certainly organizations that do a good job at distributing their goods where they are needed. Just make sure to do a little research first.
- Homeless shelters.
- Charities, such as Volunteers of America, YWCA, and IRC.
- Thrift stores, including Goodwill, Savers, and Salvation Army.
Selling unwanted clothing in good condition is another good option. Try a local consignment store or a website, such as Vestiaire, thredUP or Poshmark, or try to find a local clothing swap.
Clothing recycling
Only 13% of clothing gets recycled and the rest ends up in the landfill or is incinerated. Learn how to recycle clothing and other textiles here.
