Let cocktails (or mocktails) set a sophisticated and stylish tone for your adult Halloween party! We love the purple martini featured on this Halloween invite, and the spooky smoke twirling around the glass creates a perfect dark and moody look.

Since this invitation can be customized, you can add custom and clever Halloween party wording that tells your guests what to expect. Be sure to include a note that costumes are required to earn a cocktail to make sure everyone takes part in the fun!

If this invite isn’t quite your style, make sure to check our all our fun Halloween invitations. You’ll find themes ranging from Booze and Boos to Hocus Pocus.

Moody + Purple Halloween Party Idea

This purple and black mood board with loads of Halloween party ideas is such a treat, right? Build your entire look around the smoky and mysterious look

Perfectly Purple Cocktails

Let your Halloween-themed cocktails be the main focus of this party! Wow your guests with a blueberry martini, complete with dry ice for that smoke effect. The skeleton-hand drink on our mood board is so fun and a great way to create a self-serve cocktail station.

Another fun idea is to put together a bar cart in a corner of your dining room. Fill it with different type of mixers and garnishes, and let your guests play bartender.

Easy to Make Food

Let’s make the food easy!

Every guest will love a grazing board to snack on while they party. Add some cheap Halloween decorations to make it spooky – scatter skull heads, plastic spiders and white pumpkins around the board and it instantly transforms your food table.

Spooky Purple Halloween Décor

One of our favorite parts of this mood board is that it screams Halloween without traditional orange and black.

Using dark purple, gray and black elements in your drink, food and decorations will give this cocktail party a unique look for you and your guests. Pro tip: snag some purple lightbulbs to set the mood perfectly, for super cheap price too!
