I'm not trying to say there's a subtext like that it's somehow meaningful, I'm just saying that it's a weird choice of uniform and I wonder if it was at all determined by a costuming decision rather than pure practicality. You know, what real-world looks the author was considering--I read plenty of authors saying "I drew up a lot of practical things and then picked the one that looked coolest and most iconic." Here, "coolest and most iconic" includes a lot of belts, as is appropriate to anyone who grew up with Final Fantasy going on in the background. It's kind of like a girl having cat ears. That doesn't mean she's part of some sort of nekomimi porn, or even that they'll fall into nekomimi stereotypes, but it's interesting to see which sorts of "significant features" authors add to their characters. Go Nagai sideburns, or blue hair, or arare-megane, or anything else.
And, in this case, we have an entire cast done up in a uniform with suspenders and garter belts? Interesting choice. I wonder if it was an intentional selling point, because I know that plenty of people like those, or if it really is a zero-fanservice series with no consideration whatsoever of creating an "iconic character," as has been so important in recent shonen titles.
Anyway, I'm not asking for an answer or something, just musing.
