A tie is a strip of fabric knotted around a shirt collar and hanging down — the central accessory of the classic men's (and today women's) suit. Despite its almost purely decorative function, the tie has for centuries remained the main mark of business etiquette and occasion: it sets the tone of the whole look, and its colour, pattern and knot say a great deal about the wearer's taste and mood. Historically the tie descends from the neckcloths of 17th-century Croatian cavalrymen (hence the French cravate). The knot is an art of its own: from the classic four-in-hand to the symmetrical Windsor. The width and pattern of a tie reflect the era and style. A well-chosen tie is the finishing touch that turns a mere suit into a complete, considered look. It is a symbol of formality, status and attention to detail.
