The tie tack goes in the middle of the tie, approximately at the position of one of the shirt's buttons. It is located around the midsection or slightly higher.
The tie tack, also called a tie pin, keeps the tie in one place without moving around too much. It is a pin that consists of two parts: the embellished head on the front of the tie and the snap or chain on the back that connects to the shirt. When locating the right position for the tie, unbutton that button on your shirt. Through this button hole is where the tack connects to your shirt.
