4 Last-Minute Halloween Costumes That Start With Your Underwear
It's the 29th of October. You've left it too late for a proper costume. The fancy dress shop has nothing left but a sad inflatable dinosaur and a hat that says "WITCH" on it. Sound familiar?
Here's the thing: the best last-minute Halloween costumes don't come from a fancy dress shop. They start from the inside out - specifically, from your underwear drawer. OddBalls' Halloween 2026 collection covers four limited edition prints across underwear, socks and pyjamas, and every single one of them is the foundation of a genuinely good Halloween costume that takes about ten minutes to pull together.
No effort. No panic. No inflatable dinosaur.
1. The Ghost - Ghost Print
The costume: Classic ghost. Simple. Timeless. Impossible to get wrong.
Start with OddBalls' ghost print - available in underwear, socks and pyjamas - and you're already 80% of the way there. Add a white bedsheet with two eye holes cut out and you've got a costume so iconic it needs no explanation. No one is going to look at you dressed as a ghost and say "what are you supposed to be?"
If the bedsheet feels like too much effort (valid), just wear the ghost print pyjamas and tell everyone you're "a ghost who forgot their sheet." People will respect the commitment.
👻What to add:
- One white bedsheet, two eye holes
- Or: nothing. The print speaks for itself.
Effort level: Minimal. Maximum impact.
2. The Skeleton - Bones Print
The costume: Skeleton. The Halloween costume that never goes out of style and requires almost no explaining.
OddBalls' bones print is doing most of the work here - it literally looks like a skeleton. Wear the bones print pyjamas as your base layer, add some white face paint with dark eyes and you are, without question, a skeleton. If you can't find face paint, draw some bones on your face with an eyeliner pencil and commit to the bit.
The bones print is available in underwear and socks too, so you can go full skeleton from head to toe - bones socks, bones boxers, bones pyjamas. At that point you're not wearing a costume, you're making a statement.
💀 What to add:
- White and black face paint
- Or a black outfit over the bones underwear for a "skeleton suit" effect
Effort level: One trip to a chemist for face paint. That's it.
3. The Pumpkin - Pumpkin Print
The costume: Jack-o'-lantern. The Halloween mascot. The one that basically IS Halloween.
The pumpkin print is your foundation - wear it, and you've established the theme immediately. Add an orange top or hoodie, black jeans and if you're feeling ambitious, some orange face paint. You're a pumpkin. A well-dressed, comfortable pumpkin in soft cotton underwear or pyjamas.
The beauty of this one is the pumpkin print works as hard in the pub as it does at a Halloween party. Wear the pumpkin pyjamas to the party, take the top off on the way home, you're still dressed as a pumpkin. Versatile.
🎃 What to add:
- Orange top or hoodie
- Black jeans or trousers
- Optional: orange face paint for maximum commitment
Effort level: You probably already own orange and black clothing.
4. Scooby-Doo - Licensed Scooby-Doo Print
The costume: Pick a character. Any character. The whole Scooby-Doo gang is available.
This one's the easiest on the list because Scooby-Doo is so universally recognisable that just wearing the OddBalls x Scooby-Doo licensed print immediately communicates exactly what you're going for. But if you want to go further:
- Scooby-Doo: Brown outfit, big collar, tail optional
- Shaggy: Green top, brown flares, say "Zoinks" repeatedly
- Fred: White top, blue jeans, orange neckerchief (a piece of any orange fabric will do)
- Velma: Orange turtleneck, red skirt, glasses
- Daphne: Purple dress, green scarf
Wear the Scooby-Doo underwear or pyjamas as your base, add one or two identifying character pieces on top, and you've got a full Scooby-Doo Halloween costume in about twenty minutes. Or just wear the print and tell people you're "the mystery machine in human form."
🔍 What to add:
- One character-specific item: a scarf, a turtleneck, a neckerchief
- Commitment to saying your character's catchphrase at least once per hour
Effort level: Raid your wardrobe for one item in the right colour.
Last-Minute Halloween Costume FAQs
What are good last-minute Halloween costume ideas in the UK?
The best last-minute Halloween costumes start with what you're already wearing - or what's in your drawer. OddBalls' Halloween underwear, socks and pyjamas in ghost, pumpkin, bones, Scooby-Doo and Joker prints give you an instant costume foundation that takes minutes to build on.
What's the easiest Halloween costume to put together?
Ghost or skeleton - both require minimal effort and maximum recognition. OddBalls' ghost print and bones print pyjamas and underwear give you the base immediately; one sheet or one stick of face paint finishes the job.
Can you make a Halloween costume from underwear?
Absolutely - especially when the underwear has a Halloween print. OddBalls' limited edition Halloween prints in ghost, pumpkin, bones, Scooby-Doo and The Joker are detailed enough that they communicate the costume without needing much else. Add one or two supporting items and the look is complete.
What should I wear for Halloween if I have no costume?
Start with whatever Halloween print you have - or pick up a pair of OddBalls Halloween pyjamas or underwear. Each of the five Halloween 2026 designs works as a costume foundation: ghost print for a ghost costume, bones for a skeleton, pumpkin for a Jack-o'-lantern, Scooby-Doo for a Scooby-Doo costume, Joker for a Joker costume. Build outward from there with whatever's already in your wardrobe.
