Whether you’re planning an 18th party ideas bash or simply a Friday night dinner party, adults deserve more than the usual children’s-themed get-together. Incorporate a cool party theme that they can relate to for an event everyone will enjoy and talk about long afterward. From at-home spa days and ritzy red carpet events to cozy ski lodge parties and Moroccan decor, these expert-approved theme ideas for adults will help you create a memorable night of fun.

A Moroccan-themed party lets guests unleash their inner princess or sultan, with head ties and large sultan hats available to hire, says event planner Melissa Meluso. Decorate the space with lanterns, desert plants and drapes in white and gold. A Moroccan-inspired menu with tagines and baklava also works, along with couscous and minty drinks like Moroccan tea.

If your teen is obsessed with their favourite singer or band, host a karaoke party to let them sing their hearts out in front of their friends. You can even go all out with a legit machine to make it feel like the real thing, and give out prizes for the best singers.

This is one of the coolest party ideas that adults will love to do. Guests come dressed in their favourite drink, with creative attire like pirates if they’re drinking Captain Morgan, superheroes if they’re drinking DC or geese if they’re drinking Grey Goose. Throughout the night, guests take turns being the hero or the villain, and you could even have a costume contest at the end of the night.

Throw a Clueless-themed party to celebrate the hit TV show and iconic characters. Include the classic soundtrack, a dance floor and some vintage-inspired dress code. You can even bring in a DJ, who’ll play the theme tunes from the movie.

Take your guests back to the ’80s with this cool party theme idea. Set the scene with large disco balls, dark scenery, loud music and cloth drapes in black, red and orange. Encourage your guests to don their best ’80s gear and prepare a playlist featuring the hit songs released during that time.

Alternatively, you can have an 80s-inspired dinner party where your guests wear their favourite costumes and cook the dishes featured in the movie. You can also decorate your venue with a mannequin wearing the outfit from the film and serve ’80s-inspired drinks, like coloured mocktails, to complete the look.

Turn your backyard into a resort-staycation by transforming your space with hotel-worthy décor, Correale suggests. Greet your guests with plush robes and slippers, then serve delicious food with a farm-to-table theme.

If you want your party to have a scientific vibe, ask your guests to wear lab coats and decorate with test tubes, colourings, a laboratory-themed background and other science-inspired props, The Bash suggests. You can even set up a station with popular video games for everyone to participate in head-to-head competition. A virtual scavenger hunt is another fun way to keep your guests engaged, especially if some of your friends are unable to attend in person.
