A useful distinction
A fibre percentage describes material composition, while knit or woven construction concerns how the fabric is made. Garments with similar composition can therefore feel or behave differently. A simple material name is not a complete performance description.
Put it into practice
Record the label information separately from your observation of construction and texture. Mark anything not established by the label as an observation. Avoid turning a soft feel or familiar fibre name into a claim that the garment is suitable for every child or use.
