The Full Windsor Knot is a popular method for tying a necktie, known for its wide and symmetrical shape. It is often chosen for formal occasions, as it creates a polished and professional appearance. The knot is named after the Duke of Windsor, who popularized it in the early 20th century. To tie a Full Windsor Knot, start with the wide end of the tie on your right side, hanging longer than the narrow end on the left. Wrap the wide end around the narrow end, then bring it up through the loop around your neck and down through the knot you’ve created. Adjust for a neat finish.
