Another concept for a costume that is retro. Lightbrights are a toy that individuals of all ages may enjoy playing with, and this costume concept appears to be one that would be a lot of fun to build. Cotton balls (to make the shot glasses "glow"), multicolored plastic shot glasses, and some black and white foam board are all that are required for this project. If you really want to view it in the dark, you could even go the extra mile and make holes in the foam board and then thread little lights through those holes.
