Material selection is the most critical factor in determining the price point and target market. For high-end retail, prioritize natural fibers like Merino wool, Cashmere, or Mohair, which offer superior warmth and breathability. For mass-market or fast-fashion, look for blends such as Cotton-Acrylic or Viscose-Nylon, which provide a soft hand-feel while maintaining shape retention and cost-efficiency. Always request a Fiber Composition Analysis report to ensure the actual fabric matches the supplier's claims.
