There is a specific tie knot for just about any type of occasion, from informal, work tie knots to formal-event tie knots. The Windsor, which forms a large triangle, is a large knot meant to be worn at formal occasions. Its other names include the full Windsor and the double Windsor. The Windsor knot looks best on a tie that's worn with a wide-collared jacket.
Wrap the necktie around your neck and place the thicker end twelve inches below the thinner end.
Wrap the thicker end over the front and then over the back of the thinner end.
Pull the thicker end up and through the loop between the collar and the tie and bring the thick end to the front.
Twist the thick end of the tie so that the part that is in the back is curled.
Pull the thick end through the newly formed loop and run it in front, with the front end of the thicker part of the tie facing out.
Tuck the thick end through the loop for the third time and bring it down in front.
Pull down gently on the wide end and the knot will tighten. Slowly bring the knot up to your collar.
