Cufflinks date back to the 17th century, when men began using small chains that were fastened to the end of a gold or silver button in order to hold their shirt cuffs together (they originally used ribbons or ties). Over time, cuff links became a sophisticated accessory in menswear, often worn with tuxedos and other formal attire. Cuff links were easy to mass-produce cheaply and became even more popular after the Industrial Revolution. At this time, chains were replaced with rods and fasteners that featured easy-to-close clips. In the 19th century, cuff links became popular among businessmen of varying classes, thus expanding their use beyond just formalwear. In the late 20th century, manufacturers began to produce dress shirts and tuxedo shirts with buttons on the cuffs, causing a reduction in the use of cuff links. However, cuff links remain popular today, although they are often seen as a luxury item to be worn for special occasions rather than for everyday wear.
