How to Read a Clothing Label (And What Brands Don't Want You to Notice)

Last updated: April 2026

The label is the most honest thing about a garment. Most people never read it.

Which is a shame, because that little tag sewn into the side seam — the one you probably cut out because it itches — is one of the only places where a brand is legally required to tell you the truth. No vibes, no marketing copy, no mood boards. Just facts, regulated by law, printed in tiny type on a piece of woven nylon. If you know how to read it, you can learn more about a garment in thirty seconds than you'd get from browsing the product page for ten minutes.

So let's go through what's actually on that label, what it means, and — maybe more importantly — what's conspicuously absent.

---

What does the fiber content actually tell you?

In most countries — the US, EU, UK, Canada, Australia — listing fiber content on a clothing label is a legal requirement. The percentages must be accurate to within a small tolerance. This isn't optional branding. It's regulated.

And it tells you a lot. "100% cotton" is a different garment than "60% polyester, 40% cotton." And not all cotton is created equal either. The first breathes, wrinkles, and ages with character. The second resists wrinkles because it's majority plastic. Neither is inherently bad, but they're fundamentally different products, and you should know which one you're buying. When a brand leads with "cotton blend" in the product description but buries the 60% polyester on the tag, that's not an oversight. That's a choice.

Pay attention to the order. Fibers are listed from highest to lowest percentage. The first fiber listed is the primary material. If "polyester" comes first on a shirt being sold as "premium cotton," you've already learned something valuable about how that brand communicates.

What does "Made in" actually mean?

Country of origin is required on labels in most markets, but the language matters more than people realize.

"Made in Portugal" means the garment was substantially manufactured in Portugal — cut, sewn, finished there. "Designed in California" means someone with a laptop sat in California. The cotton may have been grown in India, spun in China, woven in Bangladesh, and sewn in Vietnam. "Designed in" tells you where the creative direction happened. It tells you nothing about where the labor happened.

"Imported" is the vaguest legal designation. It means the garment was not made domestically. That's it. It could come from a well-regulated factory in Japan or a sweatshop anywhere else. Without additional transparency from the brand, "Imported" is essentially a shrug printed on a tag. If a brand can't or won't tell you more than that, it's worth asking why.

What do those laundry symbols mean?

The care symbols on your label aren't arbitrary. They're standardized — based on ASTM and ISO standards — and they communicate what the fabric can physically handle without degrading.

The five core symbols: a tub (washing), a triangle (bleaching), a square (drying), an iron (ironing), and a circle (dry cleaning). Dots inside these symbols indicate temperature — more dots, more heat. Lines underneath indicate gentleness — more lines, gentler cycle. An X through any symbol means don't do that at all.

These exist because different fibers and constructions respond differently to heat, agitation, and chemicals. A merino wool sweater felts in hot water because heat causes the scales on wool fibers to lock together permanently. The "cold wash, lay flat to dry" instruction isn't a suggestion — it's telling you the garment will be destroyed otherwise.

When should "dry clean only" make you suspicious?

Here's where reading labels becomes a diagnostic tool.

Silk, structured blazers, garments with delicate embellishments — these genuinely need dry cleaning. But a simple unlined cotton or polyester dress with a "dry clean only" tag? That's often a red flag. It can mean the dye isn't colorfast and will bleed in water. It can mean the construction is so loose that regular agitation will pull it apart. It can mean the interfacing or trim will delaminate in a home wash. In other words, "dry clean only" on a simple garment sometimes means "we built this cheaply and a washing machine will prove it."

This isn't universal. Some brands default to dry clean recommendations as liability protection. But if you're holding a basic-construction garment made from fibers that are perfectly washable — cotton, polyester, nylon, linen — and the tag says dry clean only, it's worth questioning what about the construction can't survive water and agitation.

What's deliberately missing from your label?

Here's where it gets interesting. Labels tell you what's legally required. They don't tell you everything you'd need to make a genuinely informed decision.

Fabric weight (GSM) — grams per square meter — tells you how substantial a fabric is. A 120 GSM cotton tee is thin and borderline transparent. A 220 GSM cotton tee has body and drape. This number completely changes how a garment feels, how long it lasts, and how it looks on your body. It is almost never on the label. You'll find it on the product page of brands that want you to know, and nowhere at all from brands that don't.

Dye type — reactive dyes bond chemically to fibers and resist fading. Pigment dyes sit on the surface and fade faster (sometimes intentionally, for a washed-out look). The dye process affects colorfastness, hand feel, and environmental impact. Not on the label.

Factory-level origin — the label says "Made in India," but India is a country of 1.4 billion people with thousands of garment factories operating under wildly different conditions. Which factory? What were the working conditions? Were the workers paid fairly? The label doesn't say, and it's not required to.

The absence of this information isn't accidental. Including it would create accountability, and accountability is expensive.

What does GOTS certification actually guarantee?

GOTS — Global Organic Textile Standard — is one of the more rigorous certifications in the textile industry, and it's often misunderstood.

GOTS doesn't just certify that the raw cotton was organic. It covers the entire supply chain: spinning, weaving, dyeing, finishing, manufacturing. Every facility in the chain is audited. There are requirements for wastewater treatment, chemical inputs, worker safety, and labor practices. The fiber content must be at least 70% certified organic natural fibers to carry the GOTS label, and 95% for the "organic" grade.

This matters because "organic cotton" on its own only tells you about the farm. The cotton could be organically grown, then processed with harsh chemicals, dyed with toxic substances, and sewn in exploitative conditions. GOTS closes that gap by auditing the whole pipeline. It's not perfect — no certification is — but it's substantially more meaningful than a brand simply printing "organic" on its marketing. For a deeper look at what these labels actually guarantee, see our breakdown of the real problem with "sustainable" fashion labels.

What about OEKO-TEX Standard 100?

OEKO-TEX Standard 100 tests the finished product for harmful substances — formaldehyde, heavy metals, pesticide residues, certain dyes, and other chemicals that can cause skin irritation or worse. It's a product safety certification rather than a supply chain certification.

There are four product classes, based on how close the fabric gets to your body. Class I is for baby products (strictest limits). Class II is for items worn directly against skin. Class III is for items not touching skin directly. Class IV is for furnishing materials. The thresholds tighten as the class number drops.

One thing worth understanding: OEKO-TEX Standard 100 does not mean "chemical-free." It means the levels of tested harmful substances fall below established safety thresholds. That's a meaningful distinction. The certification is valuable — it means someone independent has tested the product and confirmed it meets safety standards — but it's not the same as saying no chemicals were used in production. Every processed textile involves chemistry. The question is whether the residues left behind are at levels that could harm you.

---

Are there other certifications worth knowing?

A few, depending on what you care about.

Fair Trade Certified focuses on labor practices — fair wages, safe conditions, community investment. It's more about the people making the garment than the materials.

Bluesign certifies that the production process meets environmental and safety standards, particularly around chemical management and resource efficiency. It's a system-level certification — it looks at the factory, not just the product.

B Corp certification evaluates the company as a whole — governance, worker treatment, environmental impact, community involvement. It's broader than textile-specific certifications and applies to the entire business, not just a single product line.

None of these are mandatory. Brands opt into them, which means they cost money and require ongoing audits. When a small brand carries these certifications, it usually means they've made a deliberate investment in transparency. When a large brand carries them on one product line but not the rest, that's worth noticing too.

How do you actually use all this?

You don't need to memorize every certification and symbol. You need a framework. Here's a simple one.

Next time you pick up a garment, check the label and ask three things. First: what's it made of, and does that match what I was told? Second: where was it made, and is the brand specific about that? Third: are there any third-party certifications, or is it just the brand's own claims?

A brand that answers all three clearly — real fiber content, specific origin, independent certifications — is a different proposition than one that gives you "premium cotton blend, imported" and a mood board. The label won't tell you everything. But it will tell you whether a brand is comfortable with you paying attention.

And that alone tells you a lot.
