Duo Fancy Dress Ideas: Costumes For Best Friends And Couples

A good duo costume has one rule: both halves have to work on their own. If one of you is only recognisable standing next to the other, you'll spend the night being asked what you've come as.

The best pairs are double acts where the shapes are different - tall and short, round and thin, loud and quiet.

Here are the pairings that get it right, from best mates to couples.

Honest note: we make cards, pin badges, prints and party decorations, not costumes.

Cartoon double acts

• SpongeBob and Patrick. The best-mate pairing - one full-body SpongeBob suit, and Patrick is a pink t-shirt, pink shorts with green flowers and a pink hat.
• Tom and Jerry, in grey and brown with ears.
• Pinky and the Brain, Beavis and Butt-Head, Ren and Stimpy.
• Rick and Morty: lab coat and blue wig, yellow t-shirt and brown trousers.
• Mario and Luigi, or Wario and Waluigi if you want the funnier version.
• More cartoon options - Read the guide

TV and film pairs

• Wayne and Waynetta Slob, or Vicky Pollard and Lou.
• Del Boy and Rodney: a sheepskin coat and a flat cap against a leather jacket.
• Jay and Silent Bob, Thelma and Louise, Wallace and Gromit.
• Mr and Mrs Smith, Danny and Sandy, Morticia and Gomez.
• Ant and Dec, which is two suits and one very smug expression.
• Bob Ross and a painting, if one of you would rather be scenery.

Funny mismatched pairs

• A burglar and a bag of swag.
• A bin and a seagull.
• A hot dog and a bottle of ketchup.
• A lifeguard and a shark, which is the low-effort under-the-sea option - Read the guide
• A sandwich and a packet of crisps.
• One person in a full inflatable suit, the other in a lanyard reading 'handler'.

Couples that don't look try-hard

• Same decade, different people - both noughties, one Britney and one Eminem.
• Same colour, different characters. It photographs as a pair without matching.
• One does the effort costume, the other does the deadpan prop version. It's funnier than both going all in.
• Avoid anything that needs you to stand together all night - you'll be apart within an hour.
• Noughties pairings - Read the guide

Making a duo costume on the cheap

• Buy one costume properly and DIY the other. One good suit plus a coloured t-shirt usually does it.
• Charity shops for the base layers, craft shop for the one detail that makes it read.
• Cardboard and a marker pen is a legitimate half of a duo costume.

How to write it so it lands

• Each half must work alone - you'll be separated within the hour.
• Different shapes read better than matching outfits.
• Buy one costume, DIY the other.
• One all-in, one deadpan prop is the funniest combination.

Frequently asked questions

What are good fancy dress ideas for two people?

Double acts where the two shapes differ: SpongeBob and Patrick, Tom and Jerry, Mario and Luigi, Del Boy and Rodney, or a mismatched pair like a bin and a seagull.

What is the best best-friend costume?

SpongeBob and Patrick is the classic - a full-body SpongeBob suit paired with a home-made Patrick in a pink t-shirt, pink shorts with green flowers and a pink hat.

How do you pick a duo costume that works?

Make sure each half is recognisable on its own. You'll be apart within an hour, and a costume that only makes sense as a pair leaves one of you explaining it all night.

What are cheap duo fancy dress ideas?

Buy one costume properly and build the other from a coloured t-shirt, charity shop basics and one good prop. Cardboard and a marker is a perfectly good second half.

Do you sell fancy dress costumes?

No. We design and print greetings cards, enamel pin badges, prints and party decorations in the UK. Costumes are recommendations from elsewhere - the only things linked to our own shop are ours.
