Sequined → It is formed from "sequin" (from French *sequin*, meaning a small coin or a decorative piece) and the suffix "-ed" (indicating a past participle or an adjective). The word "sequined" describes something that is adorned with sequins, which are small shiny discs used for decoration.
Imagine a piece of clothing that is 'decorated' ('sequin') with shiny little coins, which helps you remember that 'sequined' means covered in sequins.
