What should brands confirm before repeating a bomber jacket order?

Before repeating a bomber jacket order, brands should confirm whether the same fabric, lining, rib, zipper, buttons, labels, and packaging materials are still available. Even repeat orders can show differences if the fabric batch, dye lot, rib quality, or hardware supplier changes. Mature brands should keep an approved production record that includes fabric swatches, trim cards, color references, measurement specs, logo placement, and packing requirements. The manufacturer should compare the new pre-production sample with the previous approved sample before starting bulk production.
