A solid and wide triangular knot, the Windsor knot, sometimes also called Full or Double Windsor is the knot to know for formal occasions. Even though legend gives the paternity of this knot to the very chic Duke of Windsor, he never wore it. He only used the four-in-hand, but with wide and thick ties which made such a strong impact that the public created this knot to emulate him. This knot will fit spread collars like the Italian ones or the Windsor. This knot will work well with thinner ties. To realise this knot, make sure that the wide of your tie is much longer than the small one. The small end should be around your belly-button.
1. Start with the wide end of your tie on your left and the small one on your right.
2. Put the wide end over the small end.
3. Underneath the small end, make a loop on the right side.
4.Put the wide end underneath the loop we've just created.
5. Do the same on the left side. You now have two loops, one on the right and one on the left.
6. Roll around the two previous loops with the wide end.
7. Put the wide end up the neck loop by underneath.
8. Hold the small hand, and pull down your wide end through the new loop. Pull it gently to tighten it.
9. Adjust your knot to make sure that it is perfectly symmetrical. You might need to do it once or twice to have the desired result.
