I designed this for a friend to wear to a dress up party. People who have played Sims will recognize this as the diamond is used to identify the character selected and to which the player can give commands. It is also used to show the mood of playable Sims. I printed this in yellow because it was the only plastic I had lying around. You can paint it over or off course print it in the color you want.
