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 both a decorative and functional purpose, adding a touch of style to formal and semi-formal attire. Pocket squares come in various colors, patterns, and textures, allowing individuals to express their personal style. Traditionally associated with men's fashion, the pocket square has gained popularity among women as well. It can complement a tie or bow tie and is often used in conjunction with other accessories like cufflinks or a watch to create a polished look.
