Okay kiddo, imagine you and your friends all love to play make-believe, and sometimes you like to dress up as different characters. Well, a costume party is kind of like that, but with lots of other people too!
Everyone who goes to a costume party gets dressed up in a cool costume. Maybe someone is dressed up like a superhero, or a princess, or a spooky monster. It's like you're all wearing your favorite dress-up clothes and playing together, but with snacks and party games too.
At a costume party, you might get to play games like pin the tail on the donkey, or musical chairs, just like at a regular party. But since everyone is dressed up in fun costumes, it feels extra special and extra fun!
The best part of a costume party is getting to see all the different costumes that people come up with. You might see some really creative ideas, like a robot made out of cardboard boxes or a mermaid with a sparkly tail. And you get to show off your own costume too!
So, a costume party is just a fun way to get together with your friends and dress up in your favorite costumes. It's like a big dress-up playdate, but with lots of treats and games to make it even more fun!
