The Standard Collar Shirt is a knit, half-sleeve pattern designed for casual wear with relaxed, unisex grading across XS - 3XL. The front features a buttoned placket engineered for knits: the placket and collar are stabilized with fusible interlining applied to self fabric to control stretch, preserve collar roll, and maintain clean button alignment. The collar is cut in self fabric with fused interlining for point stability; matching buttons are standard.

Side slits are optional and executed on request, with placket and hem allowances adjusted accordingly to keep seam balance consistent. Construction is optimized for knit handling: primary assembly via overlock for secure, elastic seams, and clean hems finished on coverstitch. Buttonholes and button attachment are executed on automatic machines for uniform spacing and consistent pull strength on knit substrates. This pattern omits a back yoke and excessive shaping, relying on knit drape and relaxed ease for comfort. Fit guidance for end consumers: select usual labeled size for a relaxed silhouette; program-specific adjustments can be applied to sleeve length or hem opening without disturbing the core pattern proportions.
