Alice in Wonderland
Clothing would be a good start. Maybe then try dressing up as a character.
A humorous character.
The cheapest option would be as Adam/Eve from the book of Genesis...
Day walker
Beackam is good
No, there isn't. But it's a really good book and I strongly recommend it.
Generally, in a book a hero is a good person who does good things and is the main character. An anti-hero can also be a main character but he will do evil things.
For a baby, I would not suggest it. If it is a character in a book, go on ahead.
Here's two of my favs: Emma or Lili
The main character of the book Dalpne's Book is Dalpne.
Also read "The Longest Day" by Cornelius Ryan, it is a very good book.
