When evaluating stripe shirt fabric, you must prioritize yarn count (e.g., 40s, 50s, 60s, or 80s/2); higher counts indicate a finer, smoother hand-feel. The composition is critical—options range from 100% Long-Staple Cotton for premium breathability to CVC (Chief Value Cotton) or TC (Tetoron Cotton) blends for enhanced wrinkle resistance and durability. Additionally, verify the fabric weight (GSM), typically ranging from 100-140 GSM for standard shirting, to ensure it meets the seasonal requirements of your target market.
