This knot is the most widely used because it is very easy to tie and good for ties of all types. It makes a narrow, elongated knot, slightly asymmetric, which isn’t good for wide collar shirts. The knot is rather small on an ordinary silk tie. It looks best on tall men and men of medium height and is also recommended for men with shorter necks: thanks to its shape, the knot visually elongates the neck a bit. Due to its simplicity, the knot tends to work loose so it might require some adjustment during the day. There are several unconfirmed theories about the origin of the name. One of them suggests that drivers of four-in-hand carriages used to tie their ties this way.
What you see in the picture is a mirror reflection: you will see the same picture if you stand in front of the mirror. Drape the tie over your neck with the wide end on your right. The narrow end should be about a foot long.
Cross the wide end over the narrow end.
Bring the wide end under the narrow end to the right. Pull the knot tight after every step to prevent it from working loose.
Bring the wide end over the narrow end to the left.
Pass the wide end under the left part of the loop around your neck.
Pass the wide end downward through the loop it has formed. Tighten and shape the knot.
Adjust the position of the knot, holding it with one hand and pulling the narrow end with the other.
The Four-in-Hand knot is complete!
