A pocket square is a small piece of cloth, typically made from silk, cotton, or linen, that is folded and placed in the breast pocket of a jacket or blazer. It serves as a decorative accessory, adding a touch of style and personality to an outfit. Pocket squares come in various colors, patterns, and textures, allowing individuals to express their fashion sense. Originally, pocket squares were used for practical purposes, such as wiping the face or hands. Today, they are primarily a fashion statement, often coordinated with ties or other accessories. The tailoring of a pocket square can vary, with popular folds including the square fold, puff fold, and pointed fold.
