Increased consumer awareness around the dangers of synthetic dyes, polychlorinated biphenyls (PCBs), and phthalates in conventional clothing is fueling a drastic revolution in the fashion industry and popular clothing stores, like H&M, Levi’s, and the Gap, are beginning to turn their attention toward producing healthier and more environmentally-friendly clothing. 
How Clothing is Made with Toxic Chemicals
During the production of clothes, toxic chemicals are used in almost every step. Synthetic fabrics are dyed with man-made chemical dying agents, fabrics doused with toxins that make them immune to biodegradation, and many clothes contain buttons and accessories that contain known endocrine disruptors. Phthalates, for example, are sometimes found in buttons, and just a few of these worn on a person could, over time, contribute to hormonal imbalance. Common synthetic fabrics like nylon and acrylic are extremely toxic to the body and the environment. The Environmental Protection Agency reports that inhalation of acrylonitrile, the main chemical compound used to produce acrylic fibers, shows carcinogenic potential via inhalation. 
Formaldehyde is essentially “baked” into fabric to make it resistant to wrinkling, which is bad news because research shows that this chemical is a human carcinogen. While it’s nice to save time and not have to iron your slacks, at what cost is this convenience factor to our future health? Nonylphenols are another class of endocrine disruptors used in some dying applications, and we’re now detecting levels of this chemical in our water. It is painstakingly clear that, for the future of our health and our planet, we must advocate for a change in the way our clothing is produced. Otherwise, we will be faced with a silent environmental and health crisis, one that may take decades to overcome.
Ways You Can Produce Change
Just as with any health movement, one of the most substantial ways to assist change is to “vote with your pocketbook.” In other words, support companies that produce organic, natural clothing as much as possible. Look for clothes made from bamboo, organic cotton, or flax, and always choose clothes produced using natural dyes. Write to your favorite clothing manufacturers to inquire what they are doing to reduce their reliance on chemicals in their clothing production. Fortunately, choosing clothes made with natural fibers is becoming easier, and the more we support these companies, the faster we will see a change in the clothing industry.

What Clothing Is Toxin-Free?
When looking at your wardrobe, note that only three items are required on labels: fiber content, country of origin, and manufacturer or dealer. Specific chemicals such as formaldehyde, triclosan, and fire retardants need not be disclosed. Factory conditions are not mentioned either. Are the workers being treated fairly? The Fair Trade Certified Apparel program is the first of its kind offering consumers an opportunity to consider the social, economic, and environmental impact of their shopping decisions.

When trying to avoid synthetic chemicals, be aware that the following types of clothing indicate a higher use of chemicals such as formaldehyde, triclosan, and nanoparticles:
