When sourcing chiffon, distinguish between Silk Chiffon (luxury, high breathability) and Polyester Chiffon (durable, wrinkle-resistant, cost-effective). For B2B retail, High-Twist Polyester is preferred for its longevity. Ensure the fabric weight is specified in GSM (Grams per Square Meter); a range of 70-100 GSM is ideal for shirts to ensure they are lightweight yet not excessively sheer. Always request a Composition Lab Report to verify the percentage of spandex if 'stretch chiffon' is required.
