My daughter is (a freak-tall) eight. Every costume she loves ends up either being a bit too "Mean Girls" for Mommy and Daddy partly because of her height and partly because of what is popular for Halloween costumes. This was one that she and I agreed on because it offered full coverage and still allowed her to look like a little girl. At eight years old, I'm not wanting her to look like an overly-made-up Zombie high school student (a la Monster High) or like a promiscuous devil or Batgirl. This was cute and fit the Halloween theme in house of "Nerds from Books." (Dad and the Boy were Harry Potter, and Mom was Professor Trelawney.)
