1. Princess exactly! girly kids are into, princesses, Hannah Montana and little witches! girl tweens are into devils and grown up witches. if parents go out, they would dress up as a hot devil or a fairy! although toddler boys wear costumes like spider man, pirate, iron man and other famous super heros. teen boys go for scary stuff like scream, darkness, capes and goblins babies usually wear pumpkins and teletubbies. =)
There is no exact costume that is the most popular (as such costumes vary based on age and gender), but the "traditional" costumes like witches, ghosts, Zombies, vampires, ect. tend to be the most popular year after year.
