If you don’t already own a button-down shirt, it’s time you reconsider. A well-designed, high-quality, and ethical blouse is a staple item of an eco-friendly closet. It’s the perfect investment for your capsule wardrobe. 

But not all button-down shirts are created equal. Many are quickly churned out and made — completely unnecessarily —  with synthetic materials and in unhealthy working conditions (cue fast fashion brands). 

So, if you are in the market for a sustainable button-down shirt to complete your polished and timeless look, here’s what to look for:

Natural Materials

Many blouses are made using polyester, a fabric made from fossil fuels that is not biodegradable, can’t be recycled, and can shed toxic microfibers. You can also find a significant amount of button-downs made from rayon viscose, a fabric that made from plants that is seemingly an eco-friendly option, but is in fact very destructive and toxic

Select shirts made of natural materials, such as silk, organic cotton, or linen. Not only are they more comfortable fabrics than synthetics, but they are most likely to biodegrade. If natural materials are untreated, certified organic, and not blended with other materials, these fabrics can break down without leaving any harmful chemicals. 

Not all-natural materials are created the same, however. Although cotton is a natural and breathable material (perfect fabric for a shirt), make sure you favor organic cotton over conventional. A great tip is to look for certifications such as USDA Organic, or, even better, GOTS, which governs the entire process of growing and processing organic cotton into fabric. 

Non-toxic Dyes and Finishes

Some dyes do more harm than good. Synthetic dyes are petroleum-derived, and there’s very little governing the use of toxic azo and aniline dyes in the countries where most of our fashion is made. Some contain heavy metals or carcinogenic substances that are hazardous when inhaled or come into contact with the skin, especially if you ever sweat through your shirt.

Also, think twice about non-wrinkle finishes because they contain formaldehyde, a chemical known for its use in biology class to dissect animals that is also found in personal care items, clothes, and sheets. Studies have found that formaldehyde contact with the skin can develop a condition called dermatitis, which can cause itchy skin, rashes, and blisters.

The same goes with favoring shirts that require dry cleaning. Dry cleaners use a chemical called perchloroethylene or trichloroethylene, which according to the Environmental Protection Agency (EPA) is likely to be carcinogenic to humans. It can cause respiratory and eye irritation, headache, kidney dysfunction, and vision problems when inhaled.

We suggest you go with shirts that are machine-washable while considering natural or un-dyed colors. Or shop with brands that have labels related to chemicals, such as OEKO-TEX and bluesign. 


This trim is often made of plastic, which never degrades and becomes another type of plastic pollution in the environment. Recently the sustainable fashion industry has seen a slight increase in eco-friendly alternatives. For example, button manufacturer Knopf Budke creates buttons made out of coconut shells, mother of Pearl, buffalo horn, bone, stone nut, and wood. They are not just a sustainable alternative but are aesthetically pleasing too. For your next shirt, search for ones with biodegradable, recycled, or eco-friendly buttons. 

Add an Undershirt

We can all agree that nothing says timeless like a good white button-down shirt. But extending its life can be a challenging task when the inevitable armpit and collar stain slowly creeps up. 

We’re happy to report that there is an ethical and sustainable solution to this problem. Conscious fashion brand Numi offers sweat-proof and soft undershirts made out of Tencel that keep you feeling fresh and clean while wearing your button-downs. With this trick, you can now rock the same shirt for years to come.

And with that, here are the brands we recommend that offer well-designed, classic, non-toxic, and machine-washable button-downs.
