Maybe you took inspiration from your fave YA series and dressed up as Isabelle Lightwood from The Mortal Instruments
Or did you go as a childhood classic like Max from Where the Wild Things Are?
Maybe you went the punny route like this "Tequila" Mockingbird costume.
Whichever book inspired you to dress up, we want to see pics!
