Mermaid sequin cloth is also a great special effect costume for characters in the story that calls for brightness, shining, or "dazzling."

All you need is some sequin cloth (aka "mermaid" cloth) and a strong flashlight aimed at the wearer. Brush the sequins so that the silver shiny side reflects the light.

"an angel of the Lord came down from heaven and, going to the tomb, rolled back the stone and sat on it. His appearance was like lightning, and his clothes were white as snow. -Matthew 28:2

"Let your light shine before others" - Matthew 5:15

There he was transfigured before them. Jesus' clothes became dazzling white, whiter than anyone in the world could bleach them. And there appeared before them Elijah and Moses, who were talking with Jesus.  Mark 9:2-4
