Bow tie, a kind of clothes with a collar, is tied on the collar of a shirt and on the chest, which broadly includes bow ties. In social etiquette, a suit should be tied and the length should be at the belt buckle. If you wear a vest or sweater, the tie should be placed behind them, and the tie clip is usually sandwiched between the fourth and fifth buttons of the shirt. [1] Ties are classified by fabric, and there are also different ways to tie them, such as windsor knot, four-handed knot and cross knot.
