Final answer:
The tie clasp should be worn below the center of the tie.
Step-by-step explanation:
The four-in-hand tie is a type of necktie that is commonly worn by men. It is characterized by its long and narrow shape. The tie clasp is a decorative accessory that is used to hold the tie in place while adding a touch of style. According to traditional fashion etiquette, tie clasps should be worn below the center of the tie in a horizontal position. This means that the clasp should be placed slightly below the halfway point between the top and bottom of the tie. It should be positioned in such a way that it is visually balanced with the overall appearance of the tie.
