When evaluating this fabric, you must prioritize GSM (Grams per Square Meter), typically ranging from 140 to 220 GSM for single jersey, to ensure the weight matches your garment type. Pay close attention to the yarn count (e.g., 30s, 40s); higher counts indicate a finer, smoother hand-feel. For Jacquard patterns, verify the pattern repeat size and whether it is a knit-in design rather than a print, as this affects both durability and aesthetic depth. Additionally, ensure the spandex content (usually 5-10%) provides sufficient four-way stretch and recovery.
