Sequins are tiny, shiny embellishments made from various materials like polyester, nylon, and metal, shaped in circular, oval, or rectangular forms. These decorative elements come in flat, cupped, or sewn styles with iridescent, holographic, or opaque finishes. Originating in ancient Egypt, sequins gained popularity in the Middle Ages and Renaissance, inspiring renowned designers like Coco Chanel and Christian Dior to incorporate them into their iconic creations. Today, sequins find widespread application in fashion, accessories, home décor, crafting, and Bollywood films due to their ability to add sparkle and elegance to any design.
