This is kind of an interesting topic.
Apparently Korone can't used her fluffball outfit very often. Something to do with management not wanting her to because she had it made for herself rather than something the company made for her. Which made me curious about all of EN and their avatars. All the things they use in 3D, the smol forms, and all the stuff Ame has got is probably not official cover stuff but things they commissioned for themselves. It doesn't seem like they have problems using them whenever though.
Don't really have anywhere I'm going with that, just thought it was notable.
