It’s not hard to read about the myriad of chemicals used throughout the fashion industry – it’s much harder to see and avoid them.

In To Dye For, Adele Peters delves into the hazards present in dyes, waterproofing, and other garment additives.

At the heart of this tale lies a revelation—the many chemicals in textiles and garments today are considered to be safe at their use and concentrations. Yet, for as much as 20% of the population, these chemicals in combination with each other, can create chemical sensitivities – imagine ‘catching’ an allergy to your clothing. The symphony of dyes, fire retardants, and stain-resistant treatments—especially found together in work uniforms—emerges as the crux of the issue.

Hope lies in bio-based dye and chemical companies, like Pili.Bio, Colorifix, Lite-1, and OrganoClick. Using biology and green chemistry these innovators make effective and safe dyes and fabric treatments. While these solutions move closer to widespread availability, a question arises: How can we avoid the chemicals in our garments until then?

The first thing we can do is avoid fast-fashion brands that rely on dropshipping. Dropshipping brands don’t receive any scrutiny from import authorities, and as a result, banned substances can get through to consumers.

If you want to go further, check out the world of undyed, unbleached, untreated garments. These garments, known in the industry as "Greige goods,"  represent the least-adulterated garments available.

Here are the brands making undyed, organic cotton t-shirts and more. An ode to simplicity, sustainability, and general chemically-free-ness.

Harvest and Mill

The only producer on this list that makes colored garments without dye, Harvest and Mill is unique for their use of heirloom colored cotton, which is cotton that grows with color built-in. They also have plenty of undyed products in the natural color you would expect from undyed, unbleached cotton.

Industry of all Nations

The coolest brand on this list has a supply chain based in a single province in India, Tamil Nadu, which is a global textile and garment manufacturing center, producing 2-3% of the world's garments. IOAN offers a wide range of undyed unbleached organic cotton garments, and if you want some color, they use naturally fermented indigo to dye a handful of their products, measuring color as ‘number of dips’.

It’s worth noting that Tirupur, Tamil Nadu’s nexus of garment production was notorious for their polluting dye and bleach houses until 2012, when, after a court order, the producers achieved zero wastewater discharge (this has mostly been maintained since then, but not 100%)
