Nerd - 2019
The costume was only part of it, it was how I talked, what I said, and my behavior that made the costume awesome!
I made braces using the backs of earrings, wire, then hot glued it to a teeth whitening tray so I can take them out when needed. It look real and also affected the way I talked.
Using part of a new & clean underwear waistband, I glued it to my pants to make it look like I had a permanent wedgie.
