The Cravat was born
The bow tie originated among Croatian mercenaries during the Thirty Years' War 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. It is uncertain whether the cravat then evolved into the bow tie and four-in-hand necktie, or whether the cravat gave rise to the bow tie, which in turn led to the four-in-hand necktie.
The most traditional bow ties are usually of a fixed length and are made for a specific size neck. Sizes can vary between approximately 14 and 19 inches as with a comparable shirt collar. Fixed-length bow ties are preferred when worn with the most formal wing-collar shirts.
The cravat is a neckband, the forerunner of the modern tailored necktie and bow tie, originating from a style worn by members of the seventeenth-century military unit known as the Croats. From the end of the sixteenth century, the term band applied to any long-strip neckcloth that was not a ruff. The ruff, a starched, pleated white linen strip, originated earlier in the sixteenth century as a neckcloth (readily changeable, to minimize the soiling of a doublet), as a bib, or as a napkin. A band could be either a plain, attached shirt collar or a detachable "falling band" that draped over the doublet collar. It is possible that initially, cravats were worn to hide soil on shirts. Alternatively, it was thought to serve as psychological protection of the neck during battle from attack by a spear.

According to the 1828 encyclopedic The art of tying the cravat: demonstrated in sixteen lessons, the Romans were the first to wear knotted kerchiefs around their neck, but the modern version of the cravat (French: la cravate) originated in the 1660s. During the reign of Louis XIV of France, Croatian mercenaries were enlisted in 1660 wearing a necktie called a tour de cou.
The traditional Croat military kit aroused Parisian curiosity about the unusual, picturesque scarves distinctively knotted at the Croats' necks: "In 1660 a regiment of Croats arrived in France — a part of their singular costume excited the greatest admiration, and was immediately and generally imitated.

Unique Style
Dare To Be You In Your Own Skin
To its devotees, the bow tie suggests iconoclasm of an Old World sort, a fusty adherence to a contrarian point of view. The bow tie hints at intellectualism, real or feigned, and sometimes suggests technical acumen, perhaps because it is so hard to tie. Bow ties are worn by magicians, country doctors, lawyers and professors and by people hoping to look like the above. But perhaps most of all, wearing a bow tie is a way of broadcasting an aggressive lack of concern for what other people think.
