2 costumes 1 masque. Legal?

[TenTenPiemaster]

So i dont know if the skit idea that was proposed a while ago with one of my friends is still happening but if it does, would i be able to be involved with that AND my Kuroshitsuji skit? Idk, i asked something similar to this before, but this one isn't like I want any prizes I'll just be a part of a group.

I have a similiar question. I have an idea to use another costume in Masq (Maybe Tonks she won't go for workmanship because she is put together) and just want to have fun with it but I'm a member of a group skit too that would like to have our skit and costumes judge.
