Poll: Classroom Costumes (Patreon)

While making new classroom event, I got hit with a little dilemma. You may have noticed that lately some teaching related events were done with a costume requirement. That was partly done to save time and memory by reducing a number of CG's required for one such event.

There are multiple ways to approach such restrictions though, and I wonder if I should try one of them out, or I should stick to the old approach...

What kind of requirement would you prefer for new classroom event?
