Push flap A back and pull up through the crossed flaps. (This is similar to tying your shoes)
Tighten the knot
In your left hand, grab flap B.
Pull flab B across the knot.
Fold flab B in half, over itself. The narrow part of the tie should be directly over the knot.
Push the center of flap A through the space such that it folds over itself like flap B in order to create the second loop.
Put your fingers in the loops and grab the tabs with your thumbs.
Pull to tighten and adjust the length of the loops and tabs.
Fold the collar down and tuck lapels under the tie.
Congratulations! You are now a dapper man.
