HOW TO TIE A TIE ON YOUR MAN–Full Windsorwebsun
The full windsor knot was first invented as a way to emulate the Duke of Windsor’s uncharacteristically large tie knots. It produces a wide, symmetrical triangle with a powerful charisma tailor-made for formal events.
This is the most formal of the standard tie knots and the key is to ensure you get your proportions correct. A full Windsor works best with a spread or cutaway collar so that you get the full effect of the knot, while your jacket lapels also need to reflect this. Definitely no skinny ties or skinny lapels with this knot.
