A Circus Party

Combine a classic circus party theme with vintage decor and fun activities like face painting, photo booths, and fortune telling (you only need a willing and clever adult to fool the kids for that one!). You could even get some carnival games and tickets going if you're super ambitious. This is a theme that could really go the distance, including a full blown circus/carnival wedding.
