Halloween Party Ideas for Adults

A grown-up Halloween party fails in one of two ways: it's a normal night in with cobwebs, or it's a kids' party with alcohol. The fix is a theme with a low bar and one piece of entertainment that runs itself.

Everything here assumes adults who'll dress up if it's easy, drink more than they eat, and want to talk. Costume competition, one big game, hot food at nine.

Halloween party supplies

Banners, cake toppers and confetti we hold in the UK — the bits that make a table look done without a costume-shop trip.

Themes adults will actually dress for

  • Black tie horror — evening wear plus one gruesome detail.
  • Horror film characters, one film per couple.
  • Decades of horror: seventies, eighties, nineties.
  • Witches and warlocks — a hat and black clothes and you're in.
  • Murder mystery, with characters assigned a week ahead.
  • Gothic dinner: six people, candles, three courses, no games.
  • Anything but a costume: come as your worst work colleague.

Drinks that look the part

  • One themed punch in a big bowl beats six cocktails you have to make.
  • Blackcurrant and prosecco, a raspberry at the bottom of each glass.
  • Mulled cider — it's the end of October, everyone's cold.
  • A no-alcohol version of the punch that isn't just orange juice.
  • Black cups, orange straws, done.

Entertainment for grown-ups

  • Murder mystery kit — the single best money you'll spend.
  • Horror film quiz, teams of four, one picture round.
  • Costume competition announced at nine, prize worth winning.
  • A playlist that turns into a normal party after ten.
  • One film on mute in the back room for the people who want out.

What to write in the invitation

  • Costumes compulsory. Sorry, but they are.
  • 8pm, food at nine, prize for the best effort.
  • Bring a bottle and a reason to be frightened of you.
  • Adults only this one — the kids' party is the Sunday before.
  • Fancy dress optional but you'll regret opting out.

Frequently asked questions

What do adults do at a Halloween party?

Dress up, eat late, and play one big thing — a murder mystery or a horror film quiz. A costume competition with a real prize is what makes people actually make an effort.

What's a good adult Halloween theme?

Black tie horror: guests wear something they already own plus one grim detail. It looks brilliant in photos and nobody has to buy a costume.

How long should an adult Halloween party last?

Four to five hours. Games in the first two, food in the middle, and let it become an ordinary party after ten.
