The Windsor is a very wide and triangular tie shape. It is the knot for special occasions and suits both Italian collared or spread collared shirts. It is recommended that you choose a long tie and a waistcoat as this knot uses a lot of tie and often wont reach the belt! The tie owes its name to the Duke of Windsor who made it popular. Before you tie this knot, slide the tie around your neck after first having buttoned up the top button of your shirt and turned up the collar. The two ends of the tie must be of different lengths. The wide end must hang down much longer than the narrow end.
