What should brands prepare before starting a custom T-shirt sample?

Brands should prepare a clear tech pack, artwork files, size chart, fabric direction, logo placement, color references, and target order quantity before starting a custom T-shirt sample. A complete sample request helps the manufacturer understand the fit, fabric, construction, printing method, labeling, and packaging requirements before development starts. If the design includes screen print, embroidery, puff print, wash effects, or special trims, these details should be confirmed early. For private label T-shirts, buyers should also prepare neck label, care label, hangtag, and packing requirements. The clearer the sample brief is, the fewer revisions are usually needed during development.
