So it looked like a pie menu to pick your cap and gown for High School graduation was discarded. I added it back into the game. If you pair it with DeaderPool's MC Command Center Mod you can use the self command feature on other sims to make them match!

Attendee's, the Principal and the teachers will no longer show up in random generated formal clothes. Instead they will show up in their regular formal attire. Thank you to natethel0ser for helping me make this.
