Cinderella, then Elsa, then a bit like Tia, and not much at all like Mulan.

She and Cinderella would be soul sisters. they have to put up with frustrating things but deal with it calmly anyway (albeit Cinderella has a far worse situation and gets frustrated openly with it less), are city girls, dreamy, appreciate romance, know when to be assertive and when to be polite, etc.

Both are self-confident, outspoken, stubborn, not particularly optimistic, quite playful. Also neither is as persistent as Ariel.
