Non-Toxic Clothing, Verified Against the Certificate
I checked whether three “non-toxic” clothing brands could prove it. One could. Threadholm audits the paperwork behind non-toxic clothing claims — certificate numbers, issuing databases, and what’s actually covered. No lab testing. No guesswork.
Why Non-Toxic Clothing Needs a Verification Standard
I started paying attention to certifications the way some people start reading food labels. Once you notice how many non-toxic clothing claims have no paperwork behind them, or they use a certification without the full picture, you can’t unnotice it.
Every brand says the right words. Almost none of them show you the certificate. GOTS and OEKO-TEX mean specific, different things, and a claim can be technically true for a fabric while saying nothing about the dyes, prints, or trims on the finished piece you’re actually buying.
Threadholm is my answer to that. Not another list of non-toxic clothing brands I like the look of — a record of what I actually checked, and what the paperwork actually says.

How We Verify Non-Toxic Clothing Certifications
01 | Locate the certificate number — product page, sewn-in label, packaging, or sustainability page.
02 | Check it against the issuing body’s public database: OEKO-TEX Label Check or the GOTS certified suppliers database.
03 | Confirm validity, certificate holder, and scope — does it cover the finished product, or only a component like the greige fabric?
04 | If no number is published anywhere, we email the brand and document what they say. An unverifiable claim is a finding, not a dead end.
Verdicts describe the claim, not the product.
One Non-Toxic Clothing Brand, One Claim, Checked
Every investigation follows the same format: one product, one claim, checked against the actual paperwork. We show you the certificate, the database entry, and exactly what it does and doesn’t cover. Every piece closes with what I’d personally do — never a shoppable list.
A Verified Non-Toxic Clothing Directory
The Threadholm directory isn’t a mood board. It’s a running list of verified non-toxic clothing, built entirely from completed audits. Every entry has a certificate we checked ourselves, organized by certification type, category, and price point.
Nothing is listed because it looked right or a brand asked to be included. It’s listed because we checked, and it held up.
GOTS vs. OEKO-TEX: What Actually Makes Clothing Non-Toxic
Know Your Fibers — what non-toxic clothing actually requires, certification by certification.
GOTS
Organic fiber content plus processing standards, from farm through finished good. Covers the whole supply chain.
OEKO-TEX Standard 100
Tests the finished product for harmful substances. Doesn’t require organic fiber — a different question than GOTS answers.
Why It Matters
These aren’t interchangeable seals. Knowing which one you’re looking at, and what it actually covers, is the whole point.
How We Verify Non-Toxic Clothing Brands
Most non-toxic clothing guides rate brands on public statements and self-reported claims. Threadholm checks the underlying paperwork instead — the certificate number, the issuing database, and exactly what it covers.
