You’ve probably never thought about why your favorite neon workout leggings stay that specific shade of electric pink after fifty washes. It seems like magic. It’s actually chemistry. In her book To Dye For, Alden Wicker pulls back a curtain most of us didn't even know existed, revealing a messy, often terrifying world where the clothes on our backs are making us—and the people who make them—genuinely sick. This isn't just another "fast fashion is bad" lecture. It’s a detective story about the molecules hiding in your closet.
Honestly, the fashion industry has a massive transparency problem. We talk about carbon footprints. We talk about fair wages. But we rarely talk about the specific chemicals used to make clothes waterproof, wrinkle-free, or "stain-resistant." Wicker’s investigation started with a group of Delta Air Lines flight attendants who began experiencing mysterious rashes, hair loss, and respiratory issues after a new uniform rollout. They weren't crazy. They were being poisoned by their clothes.
The Toxic Reality Inside To Dye For
When you pick up a copy of the To Dye For book, you're basically signing up for a crash course in toxicology that you never asked for but definitely need. Wicker doesn't just throw statistics at you. She tracks down the actual scientists and victims. One of the most jarring realizations in the text is that the legal framework for regulating chemicals in clothing is essentially a sieve. In the United States, the Toxic Substances Control Act (TSCA) is notoriously weak. Most people assume that if a shirt is sitting on a shelf at a major retailer, someone has verified it’s safe to touch your skin for twelve hours a day.
That's a lie.
The garment industry uses over 8,000 synthetic chemicals. Many of these have never been independently tested for long-term human safety in the context of wearable textiles. We are talking about PFAS (the "forever chemicals"), formaldehyde, heavy metals, and endocrine disruptors. These aren't just "traces." They are functional parts of the fabric.
Think about it. Your skin is your largest organ. It’s porous. When you sweat, your pores open up. If your shirt is treated with a disperse dye—which is known to be a sensitizer—those molecules can migrate from the polyester fibers directly into your bloodstream. Wicker points out that for people with autoimmune issues or specific sensitivities, this isn't just a minor itch. It's a systemic health crisis.

Why Branding Won't Save You
A common misconception is that this is only a "cheap clothes" problem. If you buy a $200 designer blouse, it must be safer than a $5 fast-fashion tank top, right? Not necessarily. The To Dye For book dismantles this myth pretty effectively. Because the global supply chain is so fragmented, a luxury brand might use the same dye house in Bangladesh or Vietnam as a budget retailer. The "luxury" price tag often pays for the marketing and the cut of the fabric, not necessarily a cleaner chemistry profile.
Wicker highlights how even "natural" fibers can be deceptive. A 100% cotton shirt might be grown with pesticides, processed with chlorine bleach, and then finished with a formaldehyde resin to keep it from wrinkling in the shipping container. By the time it reaches your dresser, that "natural" cotton is a chemical cocktail.
The Flight Attendant Canary in the Coal Mine
The Delta Air Lines saga serves as the narrative spine of the book. It’s a perfect, tragic case study. These employees were wearing their uniforms for long shifts, often in pressurized cabins where their skin was in constant contact with the fabric. When they started getting sick, the airline and the manufacturer (Land's End) initially pushed back. It took years of grassroots organizing and independent testing to prove that the chemicals—including high levels of chromium and formaldehyde—were the culprits.
It makes you wonder about your own wardrobe. Most of us aren't wearing a heavy polyester uniform for 14 hours straight while hauling luggage, so our reactions might be more subtle. A little bit of brain fog. A random patch of eczema. A hormone imbalance that your doctor can't quite pin down. Wicker suggests that we are all part of a massive, uncontrolled experiment.
Identifying the Worst Offenders in Your Closet
If you're looking to apply the lessons from To Dye For, you have to start looking at labels differently. It’s not just about the brand; it’s about the "performance" claims.

- Wrinkle-free or Easy-care: These are almost always treated with formaldehyde-based finishes. If it doesn't wrinkle, it's probably because it's been "locked" in place with a resin that off-gasses.
- Stain-resistant or Waterproof: This is the domain of PFAS. These chemicals are linked to everything from kidney cancer to thyroid disease. If your couch or your jacket repels water like a duck's back, it’s likely coated in "forever chemicals."
- Anti-odor or Antimicrobial: Often found in athletic wear, these frequently use silver nanoparticles or triclosan. These are designed to kill bacteria, but they can also mess with your skin's natural microbiome.
The book is deeply researched, citing experts like Dr. Vyvyan Howard, a fetal and infant pathologist who explains how these toxins can even affect the next generation. It’s heavy stuff. But Wicker’s tone remains conversational and urgently practical. She isn't telling you to go live in a cave and wear burlap. She’s telling you to become a more "literate" consumer.
What You Can Actually Do About It
Reading the To Dye For book can leave you feeling a bit paralyzed. Everything seems dangerous. However, the path forward isn't about perfection; it’s about harm reduction. The industry won't change unless the demand shifts, and the demand won't shift unless we stop falling for the "performance" trap.
One of the most effective things you can do is buy second-hand. Why? Because most of the volatile organic compounds (VOCs) and excess dyes have already been washed out by the previous owner. An old, soft cotton t-shirt is significantly "cleaner" than a brand-new one stiff with factory finishes.
Another tip: Look for third-party certifications that actually mean something. "Eco-friendly" is a meaningless marketing term. "OEKO-TEX Standard 100" or "Bluesign" are actual gatekeepers. These organizations test the finished product (and the manufacturing process) for a long list of harmful substances. If a brand isn't willing to pay for that certification, you have to ask yourself why.
Wash everything before you wear it. Use a clear, fragrance-free detergent. Don't use fabric softeners or dryer sheets—they just add another layer of synthetic fragrance and chemicals designed to coat the fibers (and your skin).

The Future of Fashion Chemistry
There is a growing movement toward "bio-based" dyes and safer alternatives, but it's currently a tiny fraction of the market. Wicker’s book is a call to action for better regulation. We need laws that mirror the EU’s REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) standards, which are much stricter than anything in the US.
Until then, the burden is on us. We have to be the ones asking the hard questions at the checkout counter. We have to be the ones prioritizing our health over the convenience of a shirt that never needs an iron.
Immediate Actionable Steps for a Safer Wardrobe:
- Prioritize OEKO-TEX or GOTS: When buying new, look for these specific labels. They are the gold standard for chemical safety and organic integrity.
- Avoid "Performance" Finishes: Skip anything labeled as "anti-odor," "stain-repellent," or "non-iron." These are red flags for heavy chemical treatments.
- The Sniff Test: If a garment has a strong, "chemical" or "plastic" smell right off the rack, put it back. That’s the smell of VOCs off-gassing.
- Embrace Natural Dyes: Seek out smaller brands using indigo, madder root, or other plant-based dyes. They are safer for you and significantly better for the waterways where these clothes are made.
- Wash New Clothes Twice: Before a new garment touches your skin, wash it at least once (or twice) to remove any residual "size" or surface dyes.
The To Dye For book isn't just about fashion. It’s about the right to know what we are putting on our bodies. It’s a wake-up call that the "new clothes smell" isn't something to celebrate—it’s something to avoid. By changing how we shop, we don't just protect our own health; we force the industry to stop poisoning the planet in the name of a $10 t-shirt.
