What is the name of the opening in the cuff or neck of a garment that allows for easy dressing?

The opening in the cuff or neck of a garment that facilitates easy dressing is known as a placket. This feature is designed to allow the wearer to put on or take off the garment with convenience, often incorporating fasteners like buttons or snaps. A placket is essential in many shirt styles and often appears in various forms to accommodate different garment designs, contributing to both functionality and style.

A hem refers to the finished edge of a garment where the fabric is folded over and stitched down, primarily serving to prevent fraying and add weight to the edge, but it does not aid in dressing. A seam is where two pieces of fabric are stitched together, serving a structural purpose rather than a functional one related to dressing. A closure is a general term that refers to any fastening mechanism used to secure a garment, which may include zippers, snaps, or buttons, but it does not specifically describe the opening itself that allows for dressing. Thus, the distinction of a placket lies in its specific purpose and design in facilitating the wearing of clothing.
