How to tie a tie: Full Windsor

Step 8 Tighten

Tighten the knot by grabbing the tail and holding under the knot while you pull down on the wide end.

Then bring the knot up to the collar by pulling up on the knot while you pull down on the narrow tail.

Repeat these two motions as necessary.

You may also need to tidy up the knot by pulling down on the front of the outermost loop so that it fully covers the loops around the arms of the Y.
