Can I throw a themed Bar/Bat Mitzvah party? What are some good theme ideas?

For the party portion of the Bar/Bat Mitzvah, it is definitely okay to throw a themed party. Themed parties are wonderful because they allow you to decorate and dress up way differently than you normally would. Some good Bar/Bat Mitzvah themes include: Country hoedown, football, basketball, baseball, superheroes, groovy 60s, 1950s, Carnival in Rio, Las Vegas, circus, masquerade ball, pirates, Cinderella, New York City, Willy Wonka and the Chocolate Factory, animals, cartoons, Disney, fashion, Hawaiian Luau, and Olympic themed party.
