Fancy Dress Party Ideas: Themes, Games & Decorations
Pick a theme everyone can pull off, plan a few games nobody has to join, decorate on a budget – plus a simple timeline and an easy way to get every guest's photos the morning after.
Most costume party guides are really lists of themes. This one covers the whole night: a planning timeline, twelve themes ranked by how much effort they ask of guests, ten games that work without drinking, budget decorations, easy party food, and a simple way to collect everyone's photos.
It works for any dress-up occasion – Halloween, a themed birthday, a carnival or Mardi Gras night, or a New Year's party with a twist.
How do you plan a fancy dress party?
Costume parties need more lead time than a normal get-together, because guests need time to sort out an outfit. Weekends around Halloween and the holidays also fill up fast.

What are good fancy dress party themes for adults?
The best themes are open enough that nobody has to buy a full costume. Here are twelve, with how much effort each one asks of your guests.
| Theme | Costume effort | Decoration idea |
|---|---|---|
| 80s and 90s | low | Neon colours, cassette tapes, a disco ball |
| One colour for everyone (e.g. all yellow) | low | Balloons and lighting in that colour |
| What I wanted to be as a kid | low | Job signs on the door |
| Bad taste | low | Clashing tablecloths, plastic flowers |
| Pun costumes | low to medium | A 'guess the pun' sheet at the door |
| Circus | medium | Red and white stripes, popcorn boxes |
| Pirates | medium | Treasure chest, fishing net, fairy lights |
| Wild West | medium | Hay bales, gingham tablecloths |
| Hippie and flower power | medium | Flower garlands, tie-dye throws |
| Under the sea | medium to high | Blue lighting, paper fish, streamers as seaweed |
| Outer space | medium to high | Stars on the ceiling, foil, UV lights |
| Fairy tales and myths | high | Fairy lights, stacks of old books, candles |
What are easy last-minute costumes?
For the guest who reads the invite on the day – each of these takes about fifteen minutes from things already at home:
- Ghost: an old white sheet with two eye holes.
- Tourist: loud shirt, sunglasses, camera round the neck, a folded map.
- Gym coach: tracksuit, headband, whistle.
- Painter: old clothes with paint splashes, brush behind the ear.
- Chimney sweep: black clothes, a smudge of eyeliner 'soot', a cardboard top hat.
- Pun: a sign reading 'Smart Cookie' pinned to a shirt covered in paper cookies – pun costumes often get the biggest laughs.
- Rock star: leather jacket, black T-shirt, lots of hair gel.
- Last-second group costume: everyone wears the same colour and goes as 'a box of crayons'.
What games can you play at a costume party?
Good party games break the ice in the first hour and then run in the background. Plan fewer rather than more – and skip anything that makes someone drink or look silly against their will.
- Best costume vote: Everyone drops a slip in a box. Categories like 'most creative', 'best last-minute effort' and 'best group costume' stop the most expensive outfit winning by default.
- Photo challenges: Small tasks such as 'a photo with someone wearing the same colour' or 'the best group shot with confetti'. Find more in our party photo challenges.
- Costume bingo: A bingo card with costume types (pirate, something with feathers, someone in a wig…). First full row shouts 'Bingo!'.
- Who am I? Sticky notes with characters on foreheads; everyone else answers only yes or no.
- Themed charades: Act out things from the party theme, two teams, one minute per round.
- Guess the jar: How many sweets are in the jar? Runs all evening.
- Intro quiz: Play the first seconds of well-known party songs; first to shout the title wins a point.
- One-minute roast of the year: Volunteers give a rhyming one-minute speech about the year, the theme or themselves – never about other guests.
- Musical statues: When the music stops, everyone freezes. Whoever moves picks the next song.
- Conga line: The classic midnight moment. Anyone who'd rather watch gets to film it.
How do you decorate a fancy dress party on a budget?
Colour does most of the work. A few cheap touches go a long way:
- Streamers on door frames, lamps and chair backs – cheap and instantly festive.
- Confetti inside clear balloons rather than loose on the floor. Paper confetti is far easier to hoover up than plastic.
- Fairy lights and coloured bulbs set more mood than any banner, and low light flatters costumes.
- A dress-up box by the door: old hats, feather boas, novelty glasses. It's decoration and a rescue kit in one.
- A photo corner against a wall with a tinsel curtain and a few props. You don't need to hire a photo booth for great group shots.
What food should you serve at a costume party?
Think food people can eat standing up, with one hand, without ruining a costume:
- Sliders, mini sausage rolls, cheese skewers, veggie sticks with dips
- Nachos or a tray bake pizza cut into small squares
- A big pot of chilli or soup for later in the evening
- Cupcakes or popcorn in the party colours
For drinks, have at least one alcohol-free option that feels like a treat, not an afterthought – a fruit punch with ginger ale, or homemade lemonade. Put water on every table.
How much does a fancy dress party cost?
It depends mostly on guest numbers, food and venue, so rather than invent prices, here's a simple guide by spend level.
| Item | £ | ££ | £££ |
|---|---|---|---|
| Venue | Your own home | Community hall or club room | Hired party venue |
| Food | Potluck | Home-cooked plus a few bought treats | Caterer |
| Decorations | Streamers, confetti, fairy lights | Plus a photo corner with props | Fully themed room |
| Photos | Everyone shoots on their own phone | Digital disposable camera via QR code (free) | Hired photo booth or photographer |
How do you get everyone's photos after the party?
At a costume party everyone takes photos – and the next day they're scattered across twenty phones. Group chats often compress them, and anyone not in the chat gets nothing.
A digital disposable camera solves that. You put up a QR code, guests scan it and shoot straight from their browser, no app needed. Each guest gets a limited number of shots – a shot limit, like a roll of film – so people take fewer, better photos instead of a hundred blurry bursts.
With Filmriss, the photos are only 'developed' the next morning. That reveal is perfect for a late breakfast with friends: everyone sees what happened at the same time. Filmriss is free, keeps photos in original quality and deletes them after 90 days. See how it works as a digital disposable camera for your party.

Fancy dress party FAQ
What is the difference between a fancy dress party and a costume party?
Nothing, really. 'Fancy dress' is the usual British term and 'costume party' the American one; both mean a party where guests dress up, often to a theme.
What is the easiest fancy dress theme?
Themes guests can do from their own wardrobe: 80s and 90s, one colour for everyone, bad taste, or 'what I wanted to be as a kid'.
What games work at an adult costume party?
A best costume vote, costume bingo, photo challenges, Who am I?, themed charades and an intro quiz. None of them need alcohol, and all still work if not everyone plays.
Does everyone have to dress up?
No. Say 'costumes encouraged, not compulsory' on the invite and keep a box of hats and masks by the door.
How far ahead should I send invitations?
About four weeks before, with the theme included, so guests have time to put an outfit together.
How can I collect all the guests' photos?
Use a digital disposable camera like Filmriss: guests scan a QR code, take photos in their browser without an app, and everyone sees the pictures in a shared gallery the next morning.
