Brands can reduce custom jacket production risk by confirming all major construction details before bulk production. Jackets involve more variables than basic tops, including shell fabric, lining, interlining, zipper quality, buttons, cuffs, collars, pockets, quilting, embroidery, patches, and packaging. Before placing a bulk order, buyers should approve the sample, measurement chart, fabric standard, trim card, logo placement, and packing method. For mature brands, the most important step is not only approving the first sample, but also confirming the pre-production sample that reflects the final bulk standard.
