If you’ve ever looked at a clothing label and wondered what 90% bamboo, 10% elastane or 95% cotton, 5% spandex is actually supposed to tell you, you’re not alone. Fibre content can feel oddly technical when all you really want to know is: Will this feel soft? Will it stretch? Will it breathe? Will it hold up?
The good news is that fabric labels can be genuinely helpful once you know what you’re looking at. They won’t tell you everything about a garment, but they do offer a useful first clue about how a piece may feel, move, and fit into your everyday life.
In this guide, we’ll walk through how to understand fabric percentages in plain language, what common fibres often contribute, and how to use that information when you’re shopping online.
What a fabric label actually tells you
A fabric label lists the fibres used in a garment and the percentage of each one. Usually, the fibre with the highest percentage makes up the base of the fabric, while the smaller percentages are there to add something specific.
The biggest percentage usually tells you the main story
If a label says 90% rayon from bamboo, 10% Lycra, that usually means the bamboo-based fibre is doing most of the work when it comes to softness, drape, and overall feel. The Lycra is there to add stretch and help the garment recover its shape after wear.
If a label says 90% modal, 10% elastane, you can expect the modal to shape the feel of the fabric, while the elastane helps it move with you.
Small percentages can still make a big difference
Even 3% to 10% of a second fibre can noticeably change how a garment performs. A little elastane can make a tee feel more forgiving. A touch of nylon can add strength. A blend is not automatically a compromise — often, it’s how brands create balance.
Why fabric blends exist
It’s easy to assume that a garment made from one fibre must be “better” than a blend, but that’s not usually how clothing works in real life. Many of the pieces people reach for most often are blends, because different fibres bring different strengths.
Blends are often about balance
Brands use blends to combine qualities like:
- softness and smoothness
- stretch and recovery
- breathability and comfort
- drape and fluidity
- durability and shape retention
- easier everyday care
For example, a soft bamboo or modal knit may feel beautiful on its own, but adding elastane can make it more flexible and resilient for day-to-day wear. A structured fabric might include nylon for strength or longevity. The goal is usually not to make a fabric more complicated — it’s to make it more wearable.
A blend doesn’t automatically mean lower quality
Quality depends on more than fibre names alone. Yarn quality, knit structure, fabric weight, dyeing, finishing, and garment construction all matter too. A thoughtfully made blend can feel better, wear longer, and work harder in your wardrobe than a poorly made single-fibre fabric.
What common fibres often contribute
A label won’t tell you everything, but certain fibres do tend to show up with recognizable qualities.
Bamboo / rayon or viscose from bamboo
Bamboo-based fibres are often loved for their softness, smooth feel, breathability, and fluid drape. In many everyday knits, they create that comfortable, easy-on-the-body feeling people often describe as buttery or silky.
Cotton
Cotton is familiar for a reason. It’s often associated with breathability, softness, and everyday ease. Depending on the knit or weave, it can feel crisp, casual, lightweight, or substantial. Cotton blends can be especially useful when you want a fabric that feels approachable and easy to wear.
Modal and MicroModal®
Modal is known for its silky softness, lightweight comfort, and drape. It often feels especially smooth against the skin and can create a fluid, polished look without feeling fussy. MicroModal® takes that softness even further and is often chosen for pieces meant to feel light, luxurious, and easy to re-wear.
Elastane / spandex / Lycra
Elastane is the fibre that helps clothing stretch and bounce back. It usually appears in smaller percentages, but it can make a major difference in comfort and fit. In leggings, fitted tops, dresses, and layering pieces, elastane helps garments move with you instead of feeling restrictive.
Polyester or nylon in a blend
These fibres can add strength, structure, durability, or performance, depending on the garment. That doesn’t mean every shopper will prefer them in every situation, but in some blends they serve a practical purpose. The key is to think about what you want the garment to do, not just what you want the label to say.
How to use fibre percentages when shopping online
When you can’t touch a garment in person, fibre content becomes one helpful clue among several.
Start with the base fibre
Ask yourself what the main fibre suggests. Is it likely to feel soft and drapey, like bamboo or modal? More familiar and casual, like cotton? More structured or performance-focused, depending on the blend?
Then look at the supporting fibres
A small amount of elastane usually suggests stretch. Nylon may hint at added resilience. A blend can help you picture whether a piece is likely to skim, cling, hold shape, or move fluidly.
Pair the label with the rest of the product page
Fabric percentages work best when you read them alongside:
- product photos
- garment silhouette
- fit notes
- care instructions
- descriptions of feel, weight, or stretch
For example, a bamboo-and-lycra tee may sound soft and stretchy, but whether it feels more loungey or more polished will also depend on the cut and fabric weight. A modal dress may sound fluid, but the final drape still depends on how the fabric is knit and how the garment is designed.
What a fabric label does not tell you
This is the part that saves a lot of confusion: a label is helpful, but it is not the whole story.
A label won’t tell you fabric weight, opacity, or knit structure
Two garments can both say 90% bamboo, 10% Lycra and still feel completely different. One may be light and airy, while another feels more substantial and smoothing. That’s because fibre content doesn’t tell you the GSM, knit structure, finishing, or thickness.
A label also won’t tell you everything about quality
A garment’s longevity depends on how the fabric was made, how the piece was sewn, and how it’s cared for over time. Fibre content matters, but so do craftsmanship and care.
A gentle takeaway: use the label as a clue, not a rule
Learning how to read fabric labels can make online shopping feel a lot less like guesswork. The label gives you a starting point: which fibre leads, what supporting fibres may add, and what sort of feel or function you might expect.
From there, the best approach is to stay curious. Combine fibre content with product photos, fit details, and care notes. Think about how you want a piece to feel in your real life — soft, stretchy, breathable, drapey, structured, or easy to care for.
Because in the end, the “best” fabric isn’t about chasing a perfect label. It’s about choosing clothing that supports comfort, confidence, and long-term wear in the way that feels right for you.
