Classy adult Halloween.

If you’re thinking of hosting a classy-esque Halloween dinner party, your choices for decor are endless. Add the color white to the traditional Halloween colors (orange and black) to add a little class to your adult Halloween party. Use this trio of colors to inspire your decor. We love the idea of using teeny-tiny pumpkins as plate toppers.

Shots shots shots.

If you’re thinking about late night adult Halloween party ideas — we’re thinking shots. Use the mad scientist theme to add a little glow in the dark shot magic. Using a beaker as your serving pitcher is a fun detail. These are sure to be fan favorites.

Monster bash party invite.

Just because it’s an adult Halloween party, doesn’t mean it can’t have a little spunk. We love this Monster Halloween party invite. Sending real paper invites is a sure sign of a grown up party. It also makes it harder to flake on. (pro tip: Postable will mail them for you)


Um, ice cubes in the shape of a hand? Ghosts!! We kind of wouldn’t mind icing our drinks with these cubes even if it wasn’t Halloween.

Adult Halloween party games.

What party would be complete without some fun adult Halloween games? Put a spin on some traditional fall games to make them a little more, well — interesting. Those vodka bottles aren’t going to fish themselves.

Spooky party tunes.

Surely you’re not thinking of going into hosting your party without a ready playlist? Prepare a list of tunes to go with your Halloween feels. Better yet, use this ready made playlist for ideas for your adult Halloween party’s jams.


Jello Shots.

Going back to the mad scientist theme, these jell-o shot syringes are a neat way to serve your party’s alcohol. You can serve these during the party or make these little bad boys a parting gift. These party favors are easy to make and you’re going to need a lot, so get on that.

Photo opps.

A photo booth is always a winner, Halloween party or not! You don’t need an actual booth (unless you’re handy like that). Just put out some fun Halloween themed props and put up a sheet or some other fun backdrop… Your guests will go at it with their own phones, and the resulting images also act as great Halloween favors for adults they can look back on later.
