Sequined means decorated with sequins, which are small, shiny discs sewn onto fabric to make it sparkle and catch the light. A sequined dress glitters as the person wearing it moves, with hundreds or thousands of tiny reflective circles creating a dazzling effect.

Sequins are often made of plastic or metal and come in many colors, though silver and gold are common. They're popular on costumes for dance performances, ice skating routines, and theater productions because they shine brilliantly under stage lights. You might see a sequined jacket on a performer, a sequined pillow that changes color when you brush your hand across it, or sequined decorations on fancy clothing.

Fashion designers use sequins to create eye-catching designs, and craft stores sell sequined fabric for costumes and special projects. While sequins make clothing glamorous and festive, they also make it delicate: the tiny discs can fall off if the fabric isn't handled carefully.
