Not having read the book, it's hard to name the main characters. But based on the title, we can assume that the main characters are girls. There could be a girl who is struggling the most with the concept of perfection. Maybe there are friends or sisters among the characters who either encourage or discourage her in her journey towards perfection. It could also be that there are antagonists in the story who try to prevent the girls from achieving their idea of perfection.
Maybe there are a group of friends. For example, three or four girls with different personalities. One could be the brave and adventurous type, another the kind and empathetic one, and they all contribute to the story in their own ways.
