Mai always rock her ninja outfits and that's just the updated version of her Real Bout Special/2 look. Chun-Li is always slaying and being elegant with her master look. Cammy rocked hers, my con for her is that I wished they kept her braids, instead of being like Android 18/Blue Mary.
Well when it comes to those 3, I'd have reverted to their old looks tbh rather than pick their new outfits, unlike with C.Viper. Maybe it helps that I never really played SF4 so I have no nostalgia for her original look.
