The origin of the bow tie dates to the 17th century when Croatian mercenaries fought in support of Louis XIII against Cardinal Richelieu. As the Croats walked the streets of Paris, their brightly colored scarves caught the attention of the Court. The upper class began wearing creatively tied versions of the scarves around their necks and the bow tie was born.
Falsely named after the Duke of Windsor, the Windsor knot (also known as the full Windsor or double Windsor) is a wide triangular knot that is usually worn for formal occasions. This type of knot looks best worn with a shirt collar that is considerably cut-away.
