A fibre content label gives you useful information about a garment’s materials, but it is easy to mistake it for a complete quality rating. Read it alongside the care label, the fabric itself and the product description.
Find the percentages
A label may list several fibres, such as cotton and elastane. The percentages describe the stated composition, not how comfortable the garment will feel on every person. In the United States, the Federal Trade Commission explains that most textile and wool products must identify fibre content, country of origin and a responsible business. Rules and label formats can differ in other markets.
Separate fibre from fabric
Fibre is the raw material; fabric is created by arranging yarns or fibres in a structure. A cotton knit T-shirt and a cotton woven shirt may share a fibre name while feeling and behaving differently. The label also does not tell you precisely how long an item will last or whether its environmental impact is lower than an alternative.
Check the rest of the garment
Look at seams, buttons and the feel of the fabric, then read the cleaning instructions. If a product makes a specific performance or environmental claim, look for details and evidence instead of relying on a broad adjective. For legal requirements outside the US, consult the relevant local authority.
