Mine tend to have their day-to-day "working" outfits (Which is basically spikey Oranbegan armor for the majority of them-), a Just-Some-Average-Civilian street-clothes outfit or two, and maybe a more formal (or informal, depending-) Social Activities look for clubbing and such. Some also have Specialty outfits. Kai has one that's her motorcycle leathers and helmet. Several of the Ordis Chronos time travelers have Nova Primeva Temple Guard uniforms. Bahir has his "Beach Bum" would-be surfer-dude outfit.
Semnai is a little different... She has the usual Oranbegan, Civilian and Formal outfits, plus a very vintage-Emma-Peel style black leather cat-suit. But she has two different copies of each. One with Xhelethe, her red Thorn Blade, and one with a different, mundane sword. Why that one little switch? Because Xhel is also a player character. She's a distinct personality all on her own, has very definite *opinions* and there are just some enemies that she wants no part of being used on. Hydras, for instance. ("They are GROSS!" she says. "I do not want their goop on my blade!"-) She isn't shy about making her objections known, In those cases, Semnai sighs and switches weapons. It's easier than arguing with a cranky demon sword.
