Wakahisa, Noriko: Noriko's an odd duck. She likes everything. From gaudy/cheap/trashy to classy/fancy/pretty. As Linka's put it, Noriko has no shame, so she finds all clothing interesting to wear. Bikinis. Catsuits. Academic clothing. Asian style. Western. It's all good.

Futaba, Shiroko:
Casually, Shiroko prefers sweats, big T-Shirts, comfy pajamas. Cozy clothes you'd lull about the house in or do shopping in.

Business functions, she prefers cocktail dresses and fancy clothes.

If asked, she'd be pretty comfortable wearing more ceremonial clothes and probably has some grasp of language and symbolism for traditional women's clothing.

She actually kind of likes Gothic Lolita, and finds it fun to wear, probably because it's clothes that haven't been dictated to her by her mother.

Her glasses are entirely psychosomatic. She doesn't need them. She wore them to separate herself from Shiyoko ironically.

The Witches
The witches are supposed to be a weird combination of cyberpunk and gothic lolita. Basically frilly dresses, wires, headsets, expensive gloves. This is their work clothes.

Gwen prefers sport bras and jogging clothes or more Shiyoko-ish punky clothes when incognito.

Euphie prefers girly dresses in general. Very childish frilly things.

Mira wears pretty much the above general outfit and her source icon. And cat ears.
