Digital invitation: Halloween black cat dinner etiquette

It's half nine on a Friday. Eight people are standing in the doorway of a bar, each holding a different black dessert, and nobody is sure whether the table was booked for nine or half past. The Halloween black cat dinner etiquette problem is never the costumes — it's the information nobody wrote down. A digital invitation puts the hour, the address and the food plan in one link, and you can pick a design, write it and send it tonight from the catalogue.

Here's the wording that works: what to say about dessert, how to write two times instead of one, the dress code line that keeps everyone in, and where the confirmations should land so you stop counting replies by hand.

Nine black desserts, and the line that prevents them

If the bar is putting out dessert, say it plainly: 'nothing to bring, the bar is doing dessert.' Soften it to 'feel free to bring something' and three people turn up with a biscuit cake with plastic eyes. If the dinner is at home, split the food by what people are wearing rather than by surname — black T-shirts bring savoury, black hoodies bring sweet. Everyone gets it in two seconds, and the thread stays under ten messages.

• 'Nothing to bring, the bar is doing dessert' — a clear sentence, not 'feel free to bring something'.
• At home, split by colour: black T-shirts savoury, black hoodies sweet.
• One open question at the end — 'anything you can't eat?' — and whoever needs it will answer.
• Keep the food plan in a single paragraph, so nobody has to scroll past the memes to find it.

Digital invitation etiquette: two times and one exact address

'Door at 9:30, table at 10' is the sentence that fixes late arrivals. With a single time, half the group guesses whether it means leaving the house or sitting down. Write the exact address, the name of the bar and a map link — not 'the usual place'. If the room changes, or they move you to the back, you edit the invitation and the same link shows the new version.

Then say how the night ends. 'They close at one' is the detail that decides whether someone comes at all, and it costs one line on the first screen. This is the part most digital invitations get wrong: the information is there, but scattered across three messages and a voice note. One invitation, one list.

How to write the dress code on a Halloween black cat dinner invitation

One line covers the costume: 'black required, cat ears optional'. Optional is the word that stops the friend who owns no costume from quietly dropping out. Ban what stains — 'no fake blood at the table', because a pale tablecloth and an open bottle of syrup end in a conversation with the owner that nobody enjoys. If there's a prize for best costume, say when the vote happens: 'we vote at 11, on your phone'. Rules written in advance don't get argued about at two in the morning.

Write the rules once, put them behind one link, and the group confirms without opening a debate.

The group chat is the speaker, not the invitation

Send one message with the link and one sentence: 'everything's in here, confirm on the button.' Then leave it alone. Replies arrive inside the invitation as a single ordered list, not spread across voice notes, and you set the questions on the confirmation form yourself — a 'bringing dessert' box tells you how many you already have before you buy anything. It's a web page for your evening, not a PDF: it opens in any browser, on any phone, with nothing to install. Change the hour, the address or the dress code later and guests see the updated version, with no reprinting and no second round of messages. Write it tonight and the black cat dinner is settled before you carve the first pumpkin.
