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 an outfit. Pocket squares come in various colors, patterns, and textures, allowing individuals to express their personal style. Traditionally associated with formal wear, pocket squares can also be worn casually to enhance everyday outfits. They are often coordinated with other accessories, such as ties or bow ties, to create a cohesive look. The way a pocket square is folded can also influence its overall appearance, with various styles available to suit different occasions.
