A placket (also spelled placquet) is a finished[1] opening in the upper part of trousers or skirts, or at the neck, front, or sleeve of a garment.[2][3] The finish frequently consists of a fold of fabric that is attached to the opening in order for the fasteners (buttons, hooks, press studs) to be sewn to it. In modern usage, the term placket often refers to these double layers of fabric.[4]
Plackets are almost always used to allow clothing to be put on or removed easily but are sometimes used purely as a design element. Modern plackets often contain fabric facings or attached bands to surround and reinforce fasteners such as buttons, snaps, or zippers.
