A placket is a finished opening in a garment that allows for easy dressing and undressing. It typically features a fold of fabric that is secured with buttons, snaps, or zippers. Plackets are commonly found in shirts, blouses, and dresses, providing both functionality and style. There are different types of plackets, including the button placket, which is the most traditional, and the hidden placket, where the buttons are concealed for a cleaner look. Plackets can also vary in design, such as the French placket, which has a more polished appearance, making it popular in formal wear.
