We have over 200 DIY Halloween decorations here on Gathered, including the tutorial for this DIY Halloween banner.


4. Prepare some dangerous drinks 

What’s the first thing that pops into mind when you think ‘Halloween party ideas for adults’? Beverages of course! Create some creepy cocktails and deadly drinks to serve at your Halloween party. 

Include some alcoholic and nonalcoholic options to accommodate everyone. We love this bloody eyeball sangria by An Edible Mosaic. The lychee eyeballs are amazing!


5. DIY your Halloween costume 

You’ve got your theme and started on the decorations, now it’s time to start on your costume! Since this is an adult Halloween party you can get as creative as you like. 

Choose one of our scary Halloween costume ideas or perhaps one of our funny Halloween costumes. Whatever you choose, we know your outfit will complete the party.

Alternatively, you can easily buy a pack of Halloween party invitations like these online.


7. Prepare the pumpkins! 

It would be a sin to not have pumpkins at your Halloween party. Carve some crazy creatures and scary faces into your pumpkins and use them to decorate inside or outside your home. 

You could even set up a mini pumpkin painting station as a fun activity idea! Use our pumpkin carving ideas to create the perfect pumpkin.

8. Add an eerie glow to your home 

Lighting can really set the tone of an event, especially for Halloween parties. String glowing lights around your home in spooky colours like green, dark purple and red. 

Turn the main lights off and use your string lighting and fake candles to illuminate your home. We especially love this neon bat! 


9. Set up a petrifying prop area

Perfect for kids and adult Halloween parties, these fun props will help encourage your guests to get snapping. 

Bespoke Bride has done all the hard work for you. Simply print out their Halloween-themed props, secure sticks to the back then leave them at your party for guests to enjoy!

Got a furry friend who will be attending your Halloween party? Get them involved in the spooky antics by giving them their very own costume. 

We have 22 dog Halloween costumes here on Gathered including this adorable ghost doggie! Your guests will love seeing your pet all dressed up. 


11. Scary shot ideas 

We all know Halloween parties for adults can get a little wild… especially when the shots come out! Set up a shot bar that's as scary as your hangover will be. 

Use Sugar & Cloth’s ghost shot recipe to create these memorable ghouls.

13. DIY Halloween party favours 

Everyone loves gift giving and Halloween party favours are a nice way of showing your friends and family you care. Zsu Zsa’s Fireball shot favours sit inside tiny cauldrons – such a fun party favour! 

If you want to take things one step further, why not make them a Boo Basket? You’ll be the host of the year if you do.


14. Set the spooky mood

When hosting a Halloween party for adults it’s important to set the overall mood. Small touches such as the smell, temperature and feel of your home will add to the overall atmosphere. 

Burn some pumpkin spice candles before your guests arrive. Add some fun fog machines (Entertaining Diva shows you how) for an eerie touch. It’s the small things people remember.


15. Plan a creepy costume contest 

Costume contests aren’t just for kids; we think the adults at your party will enjoy it even more. 

Encourage their competitive nature by introducing a Halloween costume contest with categories like scariest costume, worst costume, failed costume and funniest costume. 

We love these DIY Halloween trophies by Avanti Morocha.


16. Display your fearsome foods 

Make your party food the star of the show by creating a spooktacular display to put them on. We have a huge number of Halloween table decor ideas here on Gathered, including this amazing branch set up by Cupcakes and Cashmere. 

Place your food among our decor ideas and it will add extra fright to your big night!


17. Decorate your garden

Bring the party outside with our DIY outdoor Halloween decorations. These deadly decorations will keep the outside of your house as weird as the inside. 

The best part is you can keep your outdoor display up for your trick-or-treaters too.


18. Don’t forget the sweet treats!

Halloween parties for adults need three things: food, alcohol and music. Choose a spooky Spotify playlist that sets the tone for your party. 

If your theme is based on a movie or TV show, why not play the soundtrack? Or choose one of the many premade Halloween playlists on the platform.
