Composition is a starting point, not the whole story.
Describe the hand feel, thickness, stretch, and intended use before choosing a material direction. A composition label alone does not communicate the complete construction. A fine everyday sock, a substantial casual crew, and a cushioned sports-inspired design can require different yarn combinations and knitted structures.
Review the proposed material through a sample and confirm what information is available to support the final composition description. If a special fiber, recycled-content statement, or other sourcing claim matters to the brand, request the relevant documentation for the actual product. Do not treat a marketing name as a substitute for verified material information.
