Full Sleeve T-shirts

The Full Sleeve T‑Shirt pattern is derived from a regular T‑shirt knit block and extended to a full-length sleeve calibrated to reach the wrist comfortably across sizes. Grading follows a consistent regular-fit profile from XS to 3XL with chest 36–48 inches, body length 25.5–31.5 inches, sleeve length 22.5–25.5 inches, and shoulder width 15–21 inches. The neckline is a standard crew finished in cotton lycra rib to preserve circumference and recovery through wear. Rib strips are controlled via rib cutting and roll machines to maintain stable neck opening and prevent waviness.

Primary assembly uses 4‑thread overlock for elastic, secure seams on knits; sleeve openings and bottom hem are finished cleanly with overlock, matching the specified aesthetic and durability. Pattern cutting is executed from plotted performas with layered manual cutting to hold sleeve length tolerance and shoulder alignment consistently across stacks. The block is tuned for knit fabrics typically below 220 gsm; when heavier gsm fabrics are selected, modest adjustments to sleeve length, armhole balance, and rib ratio may be applied to account for reduced drape and increased bulk. Fit guidance: choose by chest for a regular silhouette; sleeve lengths are drafted for wrist coverage without excess pooling. The provided size chart can be customized, and tolerance windows are controlled to keep chest width, shoulder increments, and sleeve reach aligned with the intended regular-fit profile.
