A cravat is a necktie, typically made of silk, that is worn with a formal evening suit. It is tied in a bow and fastened around the neck with a clasp or pin.
Cravats were first worn in the 17th century by Croatian mercenaries serving in the French army. The style quickly became popular among the French aristocracy and eventually spread to the rest of Europe. Today, cravats are still considered to be a stylish and sophisticated accessory for formal occasions.
