Her outfit used to be her schoolgirl uniform x_X; and Kanoko has dressed up and used many many costumes through her "RIG career" before landing on D*C, where she still wore her schoolgirl uniform. I really don't get this XD; Rococo as a store feels useless (just like Verge, since the main CS is the only thing they obviously want to mantain updated) but it's actually a pretty nice place, it looks better than the rest XD
Now if we are talking updated looks I think the artist did a horrid job on most of them, specially on Devin.
Unlike Verge, I feel Rococo has a viable gimmick. Verge doesn't work because it advertises supreme exclusivity and doesn't even attempt to deliver anymore. Both needed a price check at their initial launch, but Rococo adjusted faster where as they still try to pimp out Verge items for prices almost no one but the supremely rich or foolish are willing to spend.
And I don't mind seeing Rococo's storefront because it has yet to be annoying and/or obnoxious.
It's almost a little sad that it outshines any of the other "premium" stores.
