Just overall, we can see that Kanoko has a very different sense of style than Brennevin. Brennevin likes elegant, out-of-this world or old-world styles with big designs and bold colors-- most of those pieces are the focal points of an avatar, since they can simply be nothing else. (Take a look at Merlin's Hat, the Chandelier Gown-- they're HUGE and bold.)
We've seen Kanoko's style to be very cutesy and, well, almost befitting the "magical girl" genre. It could be more feminine styles, and things that we see from that genre.
Our other shops have their items separated by style: Durem Depot is Punky, H&R Wesley is formalwear, Global Imports is foreign, and so on.
Kanoko's shop would then be another divide of the items, hopefully of the quality we get from cash shop items.
