A cufflink is a decorative fastener used to hold together the cuffs of a dress shirt. Instead of buttons, some fancy shirts have holes in both sides of the cuff, and cufflinks slip through these holes to keep the fabric closed around your wrist.

Cufflinks come in pairs and often feature interesting designs: tiny works of art, family initials, or symbols representing hobbies or interests. A lawyer might wear cufflinks shaped like gavels, while someone who loves chess might wear pieces shaped like knights or rooks. Some cufflinks are passed down through families as heirlooms, carrying memories of grandparents or great-grandparents who wore them to important occasions.

People typically wear cufflinks to formal events like weddings, award ceremonies, or important business meetings. They're a small detail that shows someone took extra care with their appearance. While regular buttoned cuffs work perfectly well, cufflinks add a touch of elegance and personal style. They transform an ordinary shirt cuff into something special, the same way a carefully chosen tie or pocket square completes a formal outfit.
