When did neckties become fashionable?

Neckties became fashionable in the 17th century, with their origins traced back to Croatian mercenaries who wore knotted scarves as part of their uniforms. The style gained popularity in France during the reign of Louis XIV, who adopted the cravat as a fashionable accessory. By the 19th century, neckties evolved into the modern designs we recognize today, becoming a staple of men's formal and business attire.
