What should brands prepare before starting a custom tracksuit sample?

Before starting a custom tracksuit sample, a brand should prepare a clear design direction and production file. This usually includes the jacket and pants design, target fit, fabric type, color reference, size chart, logo placement, zipper style, elastic waistband, drawcord, pocket details, label position, decoration method, and packaging requirements. If the tracksuit uses nylon, polyester, fleece, or performance fabric, the brand should also confirm whether it needs water resistance, stretch, breathability, lining, mesh, or special finishing. Clear preparation helps the manufacturer create a more accurate first sample and reduces unnecessary revision rounds.
