Fabric composition is another critical specification that buyers scrutinize closely. The market offers several options, each with distinct cost implications and performance characteristics:
100% Cotton Denim remains the premium choice for quality-conscious buyers. It offers authentic denim feel, excellent wash effects, and natural breathability. However, it comes with higher shrinkage rates (3-5% typical) and requires pre-shrinking treatment for size stability. Pure cotton commands 15-25% price premium over blends.
Cotton-Polyester Blends (typically 60-80% cotton, 20-40% polyester) offer improved durability, reduced shrinkage, and lower cost. These are popular for mid-market positions and high-volume orders. The trade-off is reduced authenticity in hand-feel and wash effects.
Stretch Denim (cotton + 1-3% elastane/spandex) has become increasingly popular for women's jackets, offering improved fit and comfort. Amazon buyer reviews consistently praise stretch comfort, with one verified purchaser noting: "The fabric is soft and has some stretch to it. I ordered a large and it fits perfect" [3]. However, some buyers express concern when expecting 100% cotton but receiving blends.
13oz is typical but I'm looking for 15-20oz for quality positioning. Fabric weight matters most for wash effects and perceived quality.

Before you place a bulk order on the fabric, please keep in mind that you definitely need to test the washing effects first. Order 2-3 meters sample first to test shrinkage and wash results.
