Just choose a design, customize the color and wording, and you are ready to go. Check out these adult party ideas to get the best party ever!

1- Murder Mystery 

Play murder mystery games with your friends and family. Solve crime puzzles, uncover clues, and find out whodunnit. Test your detective skills and see if you have what it takes to be a master sleuth.

2- 80s Party

Throw an 80s party theme to entertain everyone and bring them back to those old days. Serve classic 80s snacks like popcorn, pretzels, and candy. Play 80s music and feature classic 80s movies or TV shows. Encourage guests to wear 80s-themed costumes.

3- Garden Party

Basically, it is important to remember that you do not have to go all out with an elaborate theme to have a good time. It is a perfect time to throw a relaxing garden party or afternoon tea party with your loved ones by decorating some string lighting and simple floral arrangements in your backyard, as well as offering some tasty finger food such as mini sandwiches, crudites, and dips.

4- Pajama Party

The best way to make your distant family members and friends feel welcome is to hold a sleepover for them. Tell everyone to wear their pajamas or onesies and provide them with some bedtime stories. You could have movie marathons or just chat casually. Perhaps you could also play truth or dare games with them.

5- Karaoke Night 

You might also want to set up a karaoke machine so that the guests can sing along. You could also set up a game in which they must guess the song’s title or artist. Guessing the lyrics would also be fun.

6- Around the World 

Guests can wear the national dress of the country they dream of going to at the reception or you can make a list of countries and ask them to choose one from the list. On the menu, have different cuisines to give the event a more worldwide feel.

7- Tea Party

The best idea for a bridal shower, Mother’s Day, or birthday party is to prepare a fancy tea party for the ladies. Set a pretty tablescape and ask the guests to wear pretty dresses, hats, and gloves, as well as finger foods that enhance the whole affair. Serve tea sandwiches, scones, and finger foods as well as hot tea or iced tea.

8- Fantasy Party

You cannot miss this party theme for adults if you are a big fan of fantasy television shows and movies. The best way to create the right vibe at your party is to create themed party food, games, and playlists that transport your guests into the world of Harry Potter, Star Wars, or Game of Thrones — or even recreate Hogwarts for a Harry Potter themed shindig.

9- Ugly Sweater 

We do not see why you cannot use this theme for any cooler weather event. Traditionally, this has been used as a Christmas party theme. Find out what threads your guests have been saving for this special occasion. 

10- Costume Party

The idea of dressing up for an event is something that everyone loves more than anything else. Throw a perfect costume party for your friends and make them enjoy the night. Allow them to come up with the best costume ever and also provide some special kind of gift for the one who wears the perfect costume.  

11- Fondue Party

Whether you are hosting a party with friends or hosting a supper club, this retro party idea is just right for you. The main course is cheese fondue and the appetizers are delicious. You can also serve a dessert fondue party or add a chocolate fondue platter for dessert. Make sure people are dressed in chunky sweaters, there is a fire going, and you are inviting them to play board games or cards with your friends.

12- Game Night

Play classic board games or card games, set up a soup bar for dinner with some classic board games and have a good old-fashioned time with a Game night at home. Drop out those board games and create some good old-fashioned fun.

13- Wine Tasting 

It would be great to have a party with a theme such as this for adults who have a large collection of wine. You can easily make this a fun party by getting different kinds or brands of wine. You can even make it a game by covering the bottles of wine and inviting your guests to guess which is which.

14- Maxian Fiesta 

Everyone loves Mexican food and drinks. That is why hosting a Mexican-themed party is the perfect idea. Start your party off with margaritas, chips, and salsa, followed by chicken tostadas, Mexican 7-layer dip, Mexican enchiladas, and nachos, or order from your favorite restaurant.

15- Après-Ski

There is nothing better than sitting in a ski lodge after skiing. That is why party planner Molly Sinsheimer suggests throwing a Sip & Shred party that combines the best of the cozy vibes of the ski lodge. Invite guests to come dressed up to après-ski attractions. Serve cold-weather favorites, such as hot chocolate and hot cider.
