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.Modern plackets often contain fabric facings or attached bands to surround and reinforce fasteners such as buttons, snaps, or zippers.This is done to protect the wearer from fasteners rubbing against their skin and to hide underlying clothing or undergarments.If the buttons are concealed by a separate flange or flap of the shirting fabric running the length of the placket, it is called a "fly front".
