I prefer
Isabelle, but
Isabella is okay. Thing is, I can't stand
Bella as a nickname to
Isabella.
Bella is okay on its own but it has a completely different feel than what
Isabella has. However
Belle doesn't seem to. I always think of
Queen Isabella when I hear the name, very elegant but rarely ever are Isabellas called by their whole name.
I don't like any of those middle names.
