Quality control for custom polo shirt production starts with a clearly approved sample. Before bulk production, the fabric, fabric weight, collar type, placket structure, button details, sleeve length, body length, logo placement, label details, size specs, and packaging requirements should all be confirmed.

During production, QC should check fabric defects, cutting accuracy, stitching quality, seam strength, collar shape, collar curling, placket alignment, button attachment, sleeve opening, side vents, shrinkage, logo placement, embroidery quality, print quality, size grading, measurement tolerance, and overall garment appearance.

Polo shirts need extra attention because collar and placket quality strongly affect the perceived value of the product. A curled collar, twisted placket, weak button attachment, uneven embroidery, or unstable shrinkage can make the polo look low quality even when the fabric is good. Finished polo shirts should be compared with the approved sample before shipment to keep bulk production consistent across first orders and repeat orders.
