Cons

Kids love transforming into a prehistoric skeleton with this clever design. The jumpsuit fits little ones aged 2-3 comfortably, and the attached tail adds a fun dino wobble as they dash about.
Once the lights go down, the skeleton print glows brilliantly. Evening trick-or-treating or a spooky party? Sorted. The detachable tail is a nice touch—kids can play with it or you can pop it off for storage.
The fabric feels soft and lets air in, so no one overheats during all that running about. Just treat this as a special occasion costume, not everyday wear, as it’s not made for endless rough play or the washing machine.
Parents love how quickly kids can get this on themselves. The straightforward design is ideal for school events or World Book Day when time’s tight.

This Ghost Face outfit is a bargain at £14.99. You get a proper scary mask, a blood-filled knife prop, and a lightweight robe that fits most kids aged 7-12.
Pros

- Great value—three decent pieces in the set
Cons

This is a classic horror costume that kids adore. The mask nails the iconic Ghost Face look, and the blood-filled knife is a massive hit—kids love showing it off.
The robe fits 10-12 year olds well, and the thin fabric actually helps keep things cool during a busy Halloween night. No one likes an overheated ghost.
This set sells out fast because it’s spooky, affordable, and instantly recognisable. The mask might swamp younger children, but older ones think it’s spot on. You get a full look for the price of a takeaway.
Quality’s better than you’d expect for the money. Your child will look properly frightening, and you won’t have to fork out loads for the effect.
K Pop Demon Hunters Costume
If your child’s into K Pop or cosplay, this costume’s a winner. It nails the character look and stands out at any party.
Pros
- Three-piece set: jacket, crop top, and skirt
- Soft polyester feels gentle on skin
- Easy care—just chuck it in the wash
Cons
- Only one character design limits variety

Kids love getting into character with this set. The white jacket screams stage performer and captures the demon hunters vibe. All the pieces fit together nicely for a complete look.
The fabric feels softer than you’d expect and doesn’t seem to irritate, even after a long night. You can wash it without worrying about colours running or the fabric bobbling.
This costume covers ages 3-13, so it’s a good shout for primary school events or themed parties. The design boosts kids’ confidence, especially if they love performing or want to stand out with their mates.
SULOLI Bat Costume
This bat costume is a great pick for kids who want something simple and reusable for dress-up after Halloween’s over.
Pros
- Wings are sturdy and don’t rip easily
- Elastic straps adjust for a comfy fit
- Wing shape looks like a real bat—not just a black sheet
Cons
- Only includes wings—you’ll need to buy other bits
- Hand wash only, which is a faff after a messy night
- Limited sizing won’t suit every age
Kids can put these on by themselves thanks to the elastic straps. No need for help—just slip them on and off they go. The straps stay put, even during wild trick-or-treating sessions.
The realistic wing shape is what makes these stand out. They actually look like bat wings, not just a generic costume add-on. Best fit is for ages 4 to 10, in our experience.
The wings hold up to plenty of running and climbing. Even after a few knocks and bumps, they still look good as new. The material doesn’t tear easily, which is a relief.
You’ll want to add some black clothes or face paint to complete the look, since it’s just the wings. But if your family loves costumes, these will get used again for school plays or parties.
SGFNXB Cat Costume Set
This seven-piece black cat costume is a steal for toddlers—adorable, easy to wear, and you won’t be scrambling for extras.
Pros
- Complete set—no need to buy more bits
- Soft plush feels nice on little ones’ skin
- Elastic bands make it quick to put on
Cons
- Best for ages 2-4, so not much room to grow
- Tail wire can bend if kids are rough
- One size might not fit every toddler perfectly
Toddlers look ridiculously cute in this. The sequined tutu adds a bit of sparkle, and the cat ears stay on even during wild dance moves.
The paw gloves are sturdier than you’d expect—they don’t get in the way of grabbing sweets or drinks. Face stickers go on easily and come off without a fuss, which is a relief for parents.
This costume’s great for more than just Halloween. We’ve used it for World Book Day, parties, and just playing at home. The plush bits wash well and hold up after a few wears.
It all packs away small, so you’re not left with a bulky costume to store. The elastic keeps its stretch, and kids can move freely—no stiff, scratchy bits to complain about.
Miyanuby Glow-in-the-Dark Skeleton Costume
This skeleton jumpsuit brings proper spooky vibes thanks to its glow-in-the-dark bones. It’s a cracking pick for trick-or-treaters who want to be seen after sunset.
Pros
- Actually glows in the dark after charging under a light
- Soft, stretchy fabric—doubles as comfy pyjamas
- Comes with matching gloves for the full skeleton look
Cons
- Glow needs regular recharging under a bright light
- Hook and loop fastening can snag on delicate clothes
- Limited sizes for older or taller children
Your little ghoul will love how this costume transforms when the lights go out. The skeleton print looks pretty cool in daylight, but under the kitchen lights for twenty minutes, the bones glowed with a proper eerie green that stuck around for hours.
The jumpsuit feels surprisingly soft against the skin. Made from a polyester blend with elastane, it stretches nicely—no awkward pulling or bunching while running about for sweets.
Getting it on is a breeze with the back closure. The gloves really finish off the skeleton look, though if your child’s on the tall side, the sleeves might come up a bit short.
The glow does fade as the night goes on, so you’ll want to recharge it if your Halloween lasts late into the evening.
Morph Alien Carry Me Costume
This inflatable alien outfit is pure comedy gold for kids aged 8-12. It creates the brilliant illusion of being whisked away by a red extraterrestrial—what’s not to love?
Pros
- Inflates in about a minute—no faffing about
- Gets guaranteed laughs at any Halloween do
- Handy pocket for stashing a phone or treats
Cons
- Needs 4 AA batteries (not included) and they’ll need swapping out now and then
- Hand wash only, so a bit more hassle to clean
- Bulky—awkward for doorways or sitting down
This costume delivers a brilliant optical illusion—kids look like they’re floating along, carried by an alien. It’s a real showstopper for trick-or-treating or parties.
Set-up couldn’t be easier. The built-in fan inflates it in seconds, and elasticated seals keep it puffed up nicely.
Your child can wear it over their normal clothes and move about freely. The fan stays quiet, so it won’t annoy anyone nearby.
The battery life is solid—over four hours is more than enough for a night out. Just don’t forget to pop in fresh batteries before heading out.
The one-size-fits-most design covers most primary school kids, but do check the size chart if your child is particularly tall or short.
Akosuntoys Grim Reaper Costume
This Grim Reaper costume packs in value with loads of accessories and clever safety features. It’s a great shout for kids aged 4-12 who want to go full spooky for Halloween.
Pros
- Full set: glowing red eyes, detachable scythe, gloves, and even temporary tattoos
- Hood has breathable mesh—no sweaty faces, plus glowing eyes don’t block vision
- Durable polyester with double stitching—stands up to rough play
Cons
- Plastic scythe is lightweight—some kids might want something sturdier
- Glowing eyes need batteries (not included)
- Runs a bit small, especially for older kids
The detail here really impressed me. The robe uses an upgraded tie-dye effect for proper faded patches, and the skeleton gloves fit snugly. There’s even a little notebook prop for added character.
The hooded mask uses mesh, so your child won’t overheat. The glowing red eyes look fantastic in the dark, but you’ll have to supply your own batteries.
The scythe is safe and light, so no worries about accidents, but it does feel a bit flimsy. The temporary tattoos are a fun bonus you can use after Halloween, too.
Spooktacular Creations Glowing Eyes Reaper Costume
This reaper costume brings proper scares with its glowing eyes and all-in-one accessories. It’s a top choice for kids aged 5-16 who want to go all out.
Pros
- Light-up glasses for a brilliant glowing effect in the dark
- Comes as a full set—no need to buy extras
- Durable polyester stands up to more than one Halloween
Cons
- Hand-wash only—cleaning takes extra effort
- Hood fabric is see-through and might feel a bit flimsy
- Chain accessory could get tangled or lost
The glowing glasses really steal the show—they fade in and out for a spooky effect that’ll get plenty of reactions. The pointed finger gloves add a creepy touch, and the robe flows nicely for that ghostly movement.
The chain rattles just enough to add to the effect without being heavy or annoying. The polyester fabric feels light and breathable, so your child can wear it for hours without overheating.
The hood stays put, and since the fabric is see-through, you can still keep an eye on your little reaper. Sizing goes from small to XX-large, so it covers a wide age range. It’s honestly a winner for any child who wants a classic reaper look.
Rubie’s Howling Ghost Costume
This classic ghost costume is a reliable pick for kids aged 5-7. Some pieces might not match the photos, but it’s still a solid option for a traditional scare.
Pros
- Soft polyester fabric—easy to move and play in
- Full set: hooded robe, mask, and gloves
- Officially licensed—meets UK safety standards
Cons
- Costume doesn’t quite match the promo photos—arm drapes are much shorter
- Some orders arrive without gloves, so double check
- Runs small for the stated age—size up if in doubt
Kids love dressing up as a classic ghost, and this one does the trick. The hooded robe gives that floating effect, and the polyester fabric won’t itch or annoy sensitive skin.
The mask adds a proper spooky touch, though you might need to replace the elastic as it feels a bit flimsy. The white gloves finish the look—if you actually get them in the box.
Comfort is where this costume really shines. Your child can run and play without restriction, and the breathable fabric keeps things cool.
Just a heads up—the product looks a bit different in real life. The arms are more like fins than the dramatic drapes shown online. Still, it’s a good shout for families after a simple, no-fuss ghost costume.

Style Highlights to Look For
Classic characters—witches, pirates, superheroes—never go out of style. They’re easy to spot and always a hit.
Trending costumes from films or telly get kids excited, but let’s be honest—they can date quickly.
DIY-friendly options let you add your own twist. Grab a basic costume and jazz it up with your own touches.

Best-selling costumes usually give you solid value for money. They mix reasonable prices with materials that actually hold up.
Versatile designs come in handy for more than just Halloween. If a costume doubles up for playtime, that’s always a win.

Frequently Asked Questions
Parents have loads of questions about safety, sizing, and picking the right costume. Let’s tackle some of the most common concerns British mums and dads mention when shopping for children’s Halloween outfits.
What are the most popular children’s Halloween costumes for this year?
Superheroes top the list for children aged 4-12. Spider-Man, Batman, and Wonder Woman come in bright colours and comfy fabrics. Kids love the freedom to move and the chance to look like their favourite characters.
Princess costumes are a big hit with ages 3-10. Elsa and Anna from Frozen, with their sparkly details and swishy skirts, seem to be everywhere. Soft materials mean fewer complaints about itching or fussing.
Dinosaur costumes are a favourite for little ones aged 2-8. The 3D spikes and tails are a nice touch, and parents like that these outfits are warm enough for chilly autumn evenings.
How can I ensure my child’s Halloween costume is safe and meets safety standards?
Check for flame-resistant labels before buying. The CE mark on UK products or a safety badge from a trusted tester gives peace of mind. Steer clear of anything made from untreated cotton or other flammable stuff.
Pick out bright costumes or add reflective tape if needed. Dark colours make it tough for drivers to spot kids after dusk. Lighter shades are just safer for evening trick-or-treating.
Masks shouldn’t block vision or breathing. Honestly, face paint is usually a safer bet than a stiff plastic mask. Also, make sure accessories have no sharp bits and fasten securely.
What are some creative DIY Halloween costume ideas for kids that I can make at home?
Ghost costumes are easy for ages 3-10—just grab a white bedsheet, cut eye holes, and hem the edges so no one trips. Kids can run about comfortably, and you won’t break the bank.
Robot costumes work well for ages 4-12 with cardboard boxes and a splash of silver paint. Stick on some LED lights or reflective tape for a bit of flair. It’s a fun project, and kids love the result.
Animal ears and tails turn everyday clothes into a costume. Felt works great for cat or dog ears for children aged 2-8. It’s a simple way to keep them warm while still looking festive.
Where can I find age-appropriate Halloween costumes for toddlers and young children?
Most UK supermarkets like Tesco, ASDA, and Sainsbury’s start stocking toddler costumes in September. You’ll find sizes from 12 months up to around 4 years, and they’re usually soft and easy to wash. Prices tend to range between £8 and £20.
Specialist fancy dress shops have a broader selection for ages 1-5. You’ll see better quality and more unusual options there. Staff usually know their stuff and can help with sizing or safety queries.
Online retailers like Amazon UK and Next deliver straight to your door and make returns simple. Their toddler ranges are huge. Always check reviews for sizing and comfort before you commit.
How do I choose the right size Halloween costume for my child to ensure a good fit?
Measure your child’s height, chest, and waist before you shop. Always go by the manufacturer’s size chart, not just their age. Sizing can be all over the place between brands.
Going a size up is usually wise for layering. It leaves room for a jumper underneath and lets them move about easily.
Look closely at sleeve and trouser lengths in the product pics. Some costumes come up short in the arms or legs. Features like elastic waistbands or Velcro are helpful for getting the right fit.
Are there any tips for helping children with sensory sensitivities enjoy dressing up for Halloween?
Start with fabrics your child already likes and introduce new textures slowly, ideally a few weeks before Halloween. Let them fiddle with costume bits and try things on for a minute or two—no pressure, just a gentle nudge.
Pick out costumes made from soft, tag-free materials, especially for kids aged 2-12. Steer clear of scratchy fabrics, tight elastics, or seams that dig in. Cotton is usually a safer bet than most synthetic stuff, to be honest.
Why not tweak their everyday clothes instead of buying a full-on costume? Pop a fun hat or cape on top of something they already love wearing. That way, they’ll still look the part without feeling uncomfortable or distracted.
Costumes are just one part of the spooky fun! If you’re looking for more ways to keep kids entertained beyond dressing up, check out our guide to the Best Halloween Toys for Kids UK.
