themed

A themed event or activity is one that has a central idea or concept. For example, a party with a pirate theme would have decorations and games related to pirates.

Themed events are super common, especially at parties and festivals. You might go to a movie theater that has a superhero-themed night where everything from the snacks to the lighting is designed to feel like you're in a comic book world. Or, if you're on vacation, you could visit an amusement park with a themed area called "Futopia" where the rides and attractions all have a futuristic twist. Themed events can also be found in everyday life, like at work, where a company might throw a holiday-themed party to get everyone in the mood.
