I'd rather a sailor moon outfit as I can't picture even a gal believing in "boobdo" dressing like the fairy), but hey, it's not like you have to use that outfit either..
She has little say in the matter, since it's not clothing, it's polymorphic tech with an intelligent core (the 'magical girl', which is quite obviously creation of the 'Well-Wisher'). Also, sailor senshi uniform makes little sense, since a) it's a good girl's outfit, and the gals are anything but; b) white is attributed, as the color of death, to the destructor outfit.
The general question of animu/nudity - while I agree that one shouldn't go overboard with this, for the risk of simply boring a sensible player - there is a point when irony changes to homage or fanboyism, and it'd be really childish to pass that point. However, on the other hand, purging the mod off all this stuff would mean betraying the basic spirit behind it. The spirit being, that if you don't want to take it, you will lose out on a good tactical game.
You can call it ideological. I consider it bad that in the current culture, all nudity and eroticism was expelled into the realm of porn, thus vulgarizing it; the basic goal of nudity here is optimism, positive vibe, not stirring base instincts. Likewise, animu was balkanized too. Long ago, productions like Akira or Ghost in the Shell were accessible to anyone; now you're either a serious person or an animu freak; and within animu, there is boring serious and fun silly, too. Why can't we have fun serious?
