Just as the strength of the human body is reliant on a strong core, the placket is the core that adds to the structural strength of the shirt’s appearance. A French placket refers to the absence of a common front placket. A plain front presents a clean look that is neither too casual nor too formal. A standard placket has a visible seam that runs vertical, next to the buttons. An inch or two of fabric is folded and sewn down the front as a separate piece, with stitches on both sides.
