I guess you mean "Favorite Best Friend of Barbie". Then why did you ad Erika here too? She is Barbie herself. Don't you know?

Do you mean best friend as themself or as friend? As themself I choose Delancey, because she's one of my favorite characters.

i pick kylie because thats my mums name and i love surfing ans she is a great friend of merliah and 2nd for me is liam becaus i have a boyfriend called liam no really i do and 3rd is taylor great fairy

Ericka is my Favourite, but i also like Rayla and Rayna too.
