Arizona: I did see one that I liked, and they turned her hair into pigtails shaped like her ears, and I thought that was genius, so I promptly stole it. Other than that, I dressed her like a proper farm hand. Overalls tank top, gloves, boots, lasso.
Oleander: Every time I see this character as a human, she either: doesn't look like herself, or her design doesn't make any damn sense. Oleander is a no nonsense 'elf' turned dark elf on a mission to save her home and the world. As such, she wears a tunic, pants, a belt to hold her tools, a cloak, gloves, an under shirt, and boots. Adventurer's clothes for the adventurer.
Tianhuo: Chinese dragon-horse dressed should probably look more Chinese than this, but I kept hair colors as they are in the game. Otherwise, she'd have black hair. Silk sleeveless shirt, sash, Wushu pants, Rubber-sole cloth shoes, arm and wrist bands.
