Cufflinks are decorative fasteners used to secure the cuffs of dress shirts. Unlike regular buttons, cufflinks are typically made from materials like metal, gold, silver, or even fabric, and they come in various designs and styles. They are often worn with formal attire, such as suits or tuxedos, and can add a touch of elegance to an outfit. To use cufflinks, one must have a shirt with French cuffs, which are longer and fold back on themselves. The cufflink is inserted through the cuff's buttonholes and then secured in place. Cufflinks can also serve as a form of personal expression, showcasing individual style or interests through unique designs.
