How to Read a Clothing Label: What Fabric Composition Really Tells You
When shopping for clothes, the composition label is one of the most useful places to look.
It tells you what fibers a garment is made from and in what proportions. But it doesn't tell you everything about its quality, comfort or durability.
A label that says 100% cotton isn't automatically a sign of a better garment. And the presence of a synthetic fiber doesn't automatically make something poor quality.
Knowing how to interpret a clothing label can help you understand what you're actually buying and make more informed choices.
Here's what to look for.
What Does Fabric Composition Mean?
Fabric composition tells you which textile fibers are present in a garment and their percentage by weight.
You might see labels such as:
100% Cotton
100% Lyocell
95% Cotton, 5% Elastane
70% Viscose, 30% Linen
These percentages describe the fiber content of the textile. They don't describe how those fibers were grown or produced, the quality of the yarn, the density of the fabric or how well the garment was constructed.
That's an important distinction.
The composition label is a useful starting point, not a complete measure of quality.
Natural, Regenerated or Synthetic: What's the Difference?
Most fibers you'll encounter fall into three broad categories.
Natural Fibers
Natural fibers occur in nature and are obtained from plant or animal sources.
Common examples include:
- cotton
- linen
- wool
- silk
- cashmere
Their properties vary considerably. Linen behaves differently from cotton, just as wool behaves differently from silk.
Even within a single fiber category, quality can vary depending on the raw material, processing and fabric construction.
Regenerated Cellulosic Fibers
Fibers such as lyocell, modal and viscose begin with naturally occurring cellulose, usually obtained from wood.
The cellulose is processed, dissolved and regenerated into textile fibers.
This means they're neither conventional natural fibers like cotton nor fossil-based synthetic fibers like polyester.
The manufacturing process matters here. Different regenerated cellulose fibers can be produced using substantially different processes and can have different properties.

Synthetic Fibers
Synthetic fibers are manufactured from polymers, most commonly derived from fossil-based raw materials.
Examples include:
- polyester
- nylon
- acrylic
- elastane
Synthetic doesn't automatically mean poor quality.
These fibers can provide useful properties such as elasticity, strength, abrasion resistance or shape retention. Their suitability depends on how and why they're being used.
Does 100% Mean Better Quality?
Not necessarily.
The phrase 100% cotton, for example, only tells you that the textile is made entirely from cotton fibers.
It doesn't tell you:
- the quality or characteristics of the cotton fibers
- how the yarn was spun
- how densely the fabric was woven or knitted
- the fabric weight
- which finishing treatments were used
- how the garment was constructed
Two garments can therefore have exactly the same fiber composition and perform very differently.
One may retain its shape and appearance for years, while another may distort, pill or wear relatively quickly.
The percentage on the label is only one part of the picture.
Why Are Fibers Blended?
Seeing several fibers on a label isn't necessarily a negative sign.
Fibers are often blended deliberately to combine different properties.
For example:
Cotton + Elastane
A small amount of elastane can provide stretch and help a fitted garment recover its shape after movement.
Wool + Synthetic Fibers
Depending on the garment and construction, synthetic fibers may be added to improve strength or abrasion resistance.
Linen + Viscose
Viscose can alter the feel and drape of linen, creating a softer and more fluid fabric.
A blend should therefore be judged by why those fibers are combined and whether the resulting fabric works well for its intended purpose, rather than simply by the number of fibers listed.
What Does 95% Cotton, 5% Elastane Actually Mean?
This is one of the most common compositions in fitted clothing.
The garment is predominantly cotton, while the elastane provides stretch.
Five percent might seem insignificant, but even a relatively small proportion of elastane can noticeably change the behavior of a fabric.
This is why it's worth reading the entire composition rather than focusing only on the dominant fiber.
The same principle applies to other blends. A secondary fiber may have been included specifically to change the garment's stretch, drape, texture or performance.
Lyocell vs TENCEL™: Why the Name Matters
Another thing that can make clothing labels confusing is the difference between a fiber type and a brand name.
Lyocell is a type of regenerated cellulosic fiber.
TENCEL™ is Lenzing's trademark for a portfolio of branded fibers, including TENCEL™ Lyocell and TENCEL™ Modal.
So TENCEL™ and lyocell aren't interchangeable terms.
A garment labelled lyocell isn't necessarily made with TENCEL™ Lyocell fibers.
This distinction matters because a branded fiber can provide additional information about its manufacturer, sourcing, production standards and traceability.
In our collection, for example, we specifically use 100% TENCEL™ Lyocell.
What the Composition Label Doesn't Tell You
This may be the most important part of reading a clothing label.
Composition alone cannot tell you whether a garment is well made.
It doesn't tell you about:
Fabric construction
How the yarns are woven or knitted can significantly influence durability, stretch, breathability and drape.
Fabric weight
The same fiber can be used to create everything from an extremely lightweight fabric to a dense, substantial textile.
Finishing
Finishing treatments can change softness, appearance, texture and performance.
Garment construction
Fiber composition tells you nothing about the quality of the seams, hems, closures or overall construction.
Fit
Even an excellent textile won't make a poorly fitting garment a good purchase.
This is why the composition label should always be considered together with the garment itself.
What Else Should You Check?
After reading the label, look at the actual garment.
Feel the fabric.
Look at how it drapes.
Check whether it's appropriate for what the garment is designed to do.
Turn the garment inside out and examine the seams and finishing.
Try it on and move in it.
And check the care instructions before buying. A garment that requires a level of maintenance you're unlikely to provide may not be the right choice for your wardrobe, regardless of its composition.

A Simple Checklist for Reading Clothing Labels
Next time you're shopping, ask yourself:
✓ What fibers is this garment made from?
✓ Is it a single fiber or a blend?
✓ If it's a blend, what might each fiber contribute?
✓ Is the fiber name generic or does it identify a specific branded material?
✓ Does the fabric feel appropriate for the garment?
✓ How does the garment need to be cared for?
✓ Does the construction match the quality suggested by the material?
A clothing label can give you valuable information. The key is knowing both what it tells you and what it doesn't.
Why We Pay Attention to the Label
For us, material choice was one of the first decisions in developing Silent Peaks.
Every piece in the collection is made from 100% TENCEL™ Lyocell, chosen for its softness, fluid drape, moisture management and strength.
But we don't believe a fiber name alone makes a garment good.
The material has to work together with the fabric construction, design, fit and manufacturing to create something worth wearing repeatedly.
That's why understanding what's on the label is useful, but understanding the garment behind it matters even more.
