Young Blonde Girl With A Black Bow Tie And Hand-held Feather Fan Shows Off On The Table Desk

A modern bow tie is tied using a common shoelace knot.
Origin and history
The bow tie originated among Croatian mercenaries during the Prussian wars of the 17th century: the Croat mercenaries used a scarf around the neck to hold together the opening of their shirts. This was soon adopted (under the name cravat, derived from the French for "Croat") by the upper classes in France, then a leader in fashion, and flourished in the 18th and 19th centuries.
