Five short questions get you to an answer: who you're going with, scary or funny, how much effort you want to put in, how comfortable you need to stay, and what you want to spend. Work through them in order and a costume falls out the other end, no scrolling past sixty ideas first. One steer before you start: inflatable and ride-on costumes made up 27% of our revenue on morphsuits.co.uk between April and August this year.

Who you're going with
Who you're with sets the brief before you've picked a costume at all. The best Halloween costumes for groups are the ones where everyone orders their own size of one shared look, not eight unrelated costumes that just happen to end up in the same photo. A couple needs two costumes that make sense side by side. Going solo removes both constraints, so it's the one case where you can go as big and as scary as you like. Our Best Halloween Costumes UK 2026 guide runs through all three cases, and if a group order is the plan, Best Group Halloween Costumes handles the harder version: matching without everyone in the identical costume.
The Fox Hunt Costume: one look, easy to multiply
A red hunt jacket over cream jodhpurs is instantly readable as a group costume the moment there's more than one of you in it. Ours is the Mens Fox Hunt Costume, £25.99: a red buttoned jacket, matching trousers, a white neck tie and a black cap. It's sized by chest measurement in two bands, Standard (41 to 44in) and Plus (44 to 48in), so a group can each check their own number against the same chart rather than guessing a generic size.
Made from 100% polyester, it's a hand wash and air dry, never the machine. The pack is the jacket, trousers, tie and hat; a riding crop or hunting horn is not included.
Scary or funny
Almost every costume sits in one of two families, and the honest way to choose is by the room rather than by what photographs best. An unsettling costume works on an adults-only night out; the same costume at a family gathering makes a young child cry. Two of the six fancy dress picks below sit on the scary side. If that's the direction, our Best Scary Halloween Costumes guide has the adult end of the range; Funny Halloween Costumes for Adults covers the other one.
Womens Nun Costume: scary without a mask
A nun costume reads as unsettling on sight, no mask or make-up required, which matters if you're driving home afterwards or supervising trick-or-treating. Ours is the Womens Nun Religious Costume, £30.99: a full-length black robe with white contrast panels, a veil, a gold belt and a cross necklace, in six sizes, Small to 3XL.
It's 100% polyester and a hand wash in cool water, with the cross necklace taken off first. If you land between two of the six sizes, take the larger one: the robe then has room for a jumper underneath on a cold October night.
Kids The Rake Morphsuit: creepy, with a hood that comes off fast
Nothing here is a mask. The skull face, hollow eyes, extended claw fingers and shadowed muscle detail are printed into the suit itself, so there's nothing for a child to put down and lose. Ours is the Kids The Rake Morphsuit, £20.99, in four sizes from 3 to 6 years up to 10 to 12 years.
It's a four-way stretch suit, 91% polyester and 9% elastane, with double-stitched seams, so a full trick-or-treat route doesn't test them. The hood closes with a quick-release hook-and-loop fit, which matters on a scary costume for a young child: it comes off in one pull if the night gets too much.
How much effort you want to put in
Effort splits into three tiers: an all-in-one costume you put on in under a minute, a costume with two or three pieces to assemble, and a full look built from separate garments and accessories. Deciding late is the norm, not the exception. YouGov's 2025 research found just 5% of British Halloween celebrators start planning two to three months ahead, while 57% start only a week before (YouGov, UK Halloween spending and shopping trends 2025). If that's you, our Best Last-Minute Halloween Costumes guide is written for the reader who has already left it late.
Giant Diplodocus Inflatable: on in a minute, fan included
This is the tier-one answer: step in, zip up, switch on the built-in fan, and there are no styling decisions left to make. Ours is the Giant Diplodocus Inflatable Costume, £30.99, in grey-blue, one size described as fitting most adults; look at the size chart on that product page before you order.
Now the unglamorous part. The fan runs on 4 x AA batteries, sold separately, giving around four hours on high-quality batteries. Buy a spare pack if you're out past midnight, because the costume goes down around you the moment the fan stops.
How comfortable you need to stay
Comfort splits into fabric, build and fit, with UK October weather behind all three, because a Halloween night here is rarely warm. Every MorphCostumes fabric costume, from the Fox Hunt jacket to the Dragon jumpsuit, is made from 125GSM+ breathable fabric, with any seam that touches skin finished in soft material and the hard side of the Velcro facing away from you. Every costume goes through over 30 measurement checks, and our QC team gets through over 500,000 checks a year on top of that. Fit is its own job: read the chart on the product page, because the bands are set per costume, and the Fox Hunt's chest ranges have nothing to do with the Nun's dress sizes.
Kids Green Dragon Jumpsuit: layering built in
A jumpsuit-based costume like this one is the easiest to layer for a cold night, since a base layer or jumper goes on underneath without changing how the costume looks. Ours is the Kids Dragon Jumpsuit Costume, £30.99: a green scale-print bodysuit with wings, a detachable tail and a hand-painted mask, sized across five age bands from 3 up to 14.
It's 100% polyester with a smooth lining and elasticated cuffs, hand wash only, with the mask off and the tail detached first. That tail comes off for the walk itself too, if your child would rather not have it catching on gateposts and car doors.
What you want to spend
Budget is the fastest filter of the five. YouGov's 2025 research found 55% of British Halloween celebrators spend under £25 on Halloween overall, with only 8% spending over £100 (YouGov, UK Halloween spending and shopping trends 2025), and the costume is usually the single biggest item in that budget. Five of our six picks land at £30.99 or less. The table below sets each one against what's actually in the pack, which is the comparison worth making.
Mens Disco Dude 70s Costume: the one to splash out on
A full retro look costs more than a single garment because there's more in the box: it's the pick for when budget isn't the deciding question. Ours is the Mens Disco Dude 70s Costume, £47.99: an iridescent long-sleeved shirt, matching flared trousers, a curly wig and sunglasses, in six sizes from Small to 3XL.
It's 100% polyester and a hand wash, with the shirt and trousers washed separately from the wig and sunglasses. Between two of the six sizes, take the larger one: flares and a fitted shirt are less forgiving than a stretch suit.

| £25 to £31 | Mens Fox Hunt Costume, £25.99 | Jacket, trousers, tie, hat |
| £25 to £31 | Womens Nun Costume, £30.99 | Robe, veil, gold belt, cross necklace |

Put the five answers together
Five short answers point you at a direction rather than one costume, and that's deliberate: only you know the room you're walking into. Turn your answers into a starting point with the table below, then check that product's own size chart before you order. If none of the six is quite it, the full Halloween Costumes range is where to look next.
| Question | If you're... | Try this direction |
|---|---|---|
| Who with | Going as a group | One shared look everyone can order in their own size, like the Fox Hunt costume |
| Who with | Going solo or as a couple | Go bigger: scary, inflatable, or both |
| Scary or funny | Wanting a real reaction | The Rake or the nun costume, no mask needed |
| Effort | Out of time | An all-in-one inflatable or Morphsuit-style piece |
| Comfort | Worried about the cold | A jumpsuit style you can layer underneath |
| Budget | Working to under £25 | Kids picks and single-garment adult costumes |
Frequently asked questions
How do I decide what to be for Halloween 2026?
Answer five questions in order: who you're with, scary or funny, how much effort, how comfortable you need to stay, and what you want to spend. Each one cuts the field. If effort is your binding constraint, an inflatable or ride-on costume is worth a look: it's the fastest costume to put on, and the category made up 27% of our revenue on morphsuits.co.uk between April and August this year.
What Halloween costume should I wear?
If you want one answer rather than a framework: a full-body one-piece, nothing to assemble and no mask to lose. Our Kids The Rake Morphsuit at £20.99 is the pick for a child who wants to be properly scary, and the Giant Diplodocus Inflatable at £30.99 is the adult pick when you want size rather than subtlety.
What can I be for Halloween on a budget?
Plenty, since most British Halloween spending stays modest: YouGov's 2025 research found 55% of Halloween celebrators spend under £25 on Halloween overall. Our Kids The Rake Morphsuit is £20.99 for a one-piece printed suit with the hood and claw hands built in, and the Mens Fox Hunt Costume is £25.99 for four pieces: jacket, trousers, tie and hat. Every costume goes through over 30 measurement checks, whichever end of the range it sits at.
What's a good last-minute Halloween costume?
An all-in-one costume you can put on in under a minute: an inflatable with a built-in fan, or a printed one-piece suit like a Morphsuit. YouGov's 2025 research found just 5% of British Halloween celebrators start planning two to three months ahead, while 57% leave it to the final week, so a costume that needs zero assembly is the realistic answer for most people, not the exception.
