When sourcing jersey fabric, the price is primarily determined by material composition (e.g., 100% cotton, polyester-spandex blends, or rayon) and fabric weight (GSM - Grams per Square Meter). For high-end apparel, prioritize combed cotton over carded cotton to ensure a smoother surface and less pilling. Always verify the yarn count (e.g., 30s, 40s); a higher yarn count typically results in a finer, more expensive fabric. Additionally, check for colorfastness (Grade 4 or higher) and shrinkage rates (ideally <5%) to ensure the fabric maintains its integrity after washing.
