Malia is too close to Miley. Her list seems pretty barren, to be honest.
Malia, try Delia or Dahlia.
Mckenna, try Emma or Sienna
Avery, try Lyra or Ariana.
Shelby, try Elsie or Ella.
Middles that have the same vibe as Nicole...
I really like Miley & Lyra the best. But I also like Miley & Emma and Miley & Elsie.
I think your friend should start doing some lurking on Namberry because her list really, really needs more to it.
