A custom shirt manufacturer brief should name the product family first: pique or jersey polo, woven casual or oxford shirt, or henley. These share a collar or placket language but not the same fabric, machine setup or measurement priorities. Polo programs usually hinge on collar stand stability, placket clean-up and jersey GSM. Woven shirts need yarn count or fabric weight, interlining decisions and button security. Henleys need placket length, rib or jersey body matching and recovery at the opening. Write the intended retail use—golf, streetwear, workwear-casual or dress-casual—so the OEM team can propose constructions that fit the use, not only the photo reference.
MOQ is 100 pcs per color per design. Confirm how that minimum applies when you split sizes or when a second color is added later. Samples typically take about 7 days once the brief and materials are confirmed; unresolved fabric holds do not count as production delays on the factory side.
