How Can Brands Specify Sleeve Length on Men's Workout T-Shirts?

Specify tee sleeve length from clearly identified shoulder or neck reference points.

The factory needs clear instructions for component dimensions, placement, seam construction, and permitted variation. Check the detail against an approved reference and movement trials, especially at high-stress joins; small assembly differences can affect symmetry, comfort, or durability even when the overall garment looks acceptable. Use the same measuring convention throughout.
