I'd definitely use primarily, if not exclusively Bard. Charisma casting is definitely her thing. Wisdom really isn't (her Insight check seems pretty lousy). No Sorcerer subclasses really work. Feylock is a bit too trickery oriented, to my way of thinking.

Plus Bards are all about singing and so is Snow White.

I can't make up my .ind between Glamour and Lore, though.
