I talked to the boss yesterday, and he likes the idea of me having a variant costume. Note that this is besides the previous idea of me having a more formal version for events in which I represent the Department of Superhuman Studies.
What we are talking about here is a variant of my regular everyday costume, this time with more of an emphasis on the brown of my white/brown/yellow color scheme. We both decided that we don't want simply a brown version of my current costume, but not necessarily something completely different, either.
Anyway, he said he'll work on it. If he gets something going, I'll let you all know. :-)
If this all works out like I hope, then I'll have 3 different costumes! :-D
