Schwarzkopf: This season’s showstopper. But leave the plastic guns at home, please.

Ghost: Bedspread chic is cheap, simple and fun. Just be careful not to look like a Klan nightrider.

Little Mermaid: With Ninja Turtles, last year’s big hit. Walking is tough, though.

Princess: No little girl ever looked bad like this. Also popular, as ever: the ballerina.
