A pocket square is a small square piece of fabric (silk, cotton or linen) placed in the breast pocket of a jacket as a decorative accent. It is a refined detail of the classic men's wardrobe that adds completeness, individuality and a note of elegant light-heartedness to a look. Unlike a tie, a pocket square is not obligatory, so it is a mark of true attention to style. It is folded in various ways (from a strict straight fold to a lavish 'puff'), and its colour and pattern may echo other details of a look but need not exactly match the tie.
