When sourcing male and female clothing, the material composition is the primary determinant of cost and durability. For high-end markets, prioritize natural fibers like 100% combed cotton, mulberry silk, or Grade A cashmere. For activewear or fast fashion, ensure synthetic blends (polyester/spandex) have a minimum GSM (Grams per Square Meter) appropriate for the season—typically 180-200 GSM for T-shirts and 280-350 GSM for hoodies. Always request a Fabric Composition Test Report (e.g., SGS or ITS) to verify that the label matches the actual fiber content.
