This is a regular-fit, long-sleeve button-up shirt with a button-down collar, a chest pocket, clear buttons, and adjustable cuffs. It's made from mid-weight woven cotton, and while the specific GSM (grams per square meter) may vary due to transition, it's designed with side seams and a back yoke for added comfort and style. The shirt is also pre-shrunk to minimize shrinkage, ensuring a consistent fit over time.
