Keira is right-handed.Here is the proof.
1) Usually all the Barbie-played characters are right-handed.
2) Keira needs to hold the microphone with the left hand as she moves her right hand while singing if you observe the song Here I am.(I am not being rude)
3) Before she starts singing,she holds the microphone in the right hand.
4)If you are not satisfied,let me give you one more proof,When Keira enters her room,she removes her wig and picks up a shoe with her RIGHT hand.I'm sorry if I can't satisfy you
