Not sure what's changed for most of them, but all of Ditsy's clown look is kind of just gone. I miss the old outfit. I also miss Bon's older look. I feel like it had a lot more flavor to it. I think some of these could be casual outfits for them, that would be cool, but their main outfits? Heck no, they feel so watered down!
The idea was too unifiy them as a band. Before they looked more like they were a part of the circus (very different and contrasting the others.) This reference sheet being in black and white doesn't really do them justice. And I will say the previous designs, in isolation, looked great, just not as good together as they are now.
I kinda felt like the whole deal was them being more of a split up group. They obviously interact with each other as members of the building, but they each have their own booth separate from each other and so aren't really one unified attraction or band or anything. Definitely would be better to see it with some colors. I still think it needs a lot more flair, and Ditsy's whole thing is totally gone. They're not even a "band" anyways, afaik only Bon is musical in nature.
