The back collar groove is a subtle yet refined detail in high-quality shirts. It allows the collar to fold more naturally and reduces strain on the fabric, helping it maintain its shape over time. This intelligent construction enhances durability, ensuring the collar remains crisp and structured with repeated wear.

Additionally, the groove minimizes pressure and friction at the back of the neck, increasing overall comfort. Often overlooked in mass-produced garments, this feature is a hallmark of thoughtful craftsmanship—where engineering meets elegance to improve both form and feel.
