Halloween Costume Ideas 2026 : 50 Looks for Adults, Couples and Groups

Halloween 2026 falls on a Saturday, which means parties rather than a quick doorstep appearance — and costumes that need to survive a full night out. Here are 50 Halloween costume ideas for adults, couples, groups and kids, from this year's trending looks to outfits you can put together for under £20.

A Saturday Halloween changes what people buy. Costumes get worn for six hours instead of one, they get photographed, and they need to work in a crowded room rather than on a dark street. Comfort and silhouette matter more than they usually do, and group themes get far more attention because more people are out together.

Everything below is grouped by who you're dressing — pick a section and skip the rest. Every idea links to the matching category if you'd rather buy the outfit than assemble it.

Trending for Halloween 2026

These are the looks with the most momentum this year, driven by what people have been streaming and the films landing in cinemas. They're also the costumes that sell out first, so decide early if one of these is your pick.

1. KPop Demon Hunters. The biggest new costume of the year, and it works solo or as a group. Stage outfits, bold makeup and a strong wig do most of the work. KPop Demon Hunters costumes
2. Villains instead of heroes. With Doctor Doom front and centre this year, villain looks are pulling ahead of the heroes they fight. Capes, armour and heavy makeup. Superhero and villain costumes
3. Greek mythology. Draped white fabric, gold cord, laurel and a metallic cuff. Cheap to assemble, photographs beautifully, and almost nobody else will have it.
4. Wednesday Addams. Still one of the most requested looks three years running — black collared dress, plaits, flat shoes. Wednesday and Addams Family costumes
5. Wicked. Green face paint and a black hat, or the pink gown if you'd rather be the other one. Reliable as a pair. Wicked costumes
6. Classic horror, played straight. Gore is on the way down this year. A well-made vampire or a proper Victorian ghost beats fake wounds. Horror movie costumes
7. Y2K throwback. Low-rise everything, butterfly clips, frosted eyeshadow. Barely a costume, which is the appeal.
8. Day of the Dead. Sugar skull makeup with marigolds and a black dress or suit. The one look on this list that never dates.

Halloween costume ideas for women

The strongest women's looks this year are the ones with a clear silhouette that reads across a dark room. A good wig lifts a cheap outfit more than an expensive dress does, so if you only upgrade one thing, upgrade that.

1. Witch, done properly. Structured black dress, wide-brim hat, dark lip. The most-bought women's costume every year for a reason. Women's witch costumes
2. Vampire countess. High collar, red-lined cape, pale base and fangs. Women's vampire costumes
3. Gothic Victorian. Lace, corsetry and a veil — no blood needed. Women's gothic costumes
4. Skeleton bodysuit. Warm, comfortable for a full night, and glows under UV lighting. Women's skeleton costumes
5. Zombie bride. A charity-shop white dress plus grey-toned makeup. Highest impact for the lowest spend on this list. Women's zombie costumes
6. Red devil. Horns, tail, red dress. Instantly readable, which matters in a packed room. Women's devil costumes
7. Harlequin clown. The clown look without the horror, in diamond patterns and pom-poms. Women's clown costumes
8. Grim reaper in white. The standard black robe, inverted. Unexpected, and it photographs far better.

Halloween costume ideas for men

Men's costumes live or die on the mask or the makeup. The outfit is usually simple — a robe, a suit, a jumpsuit — and the face does the work. Budget accordingly.

1. Killer clown. Still the most-searched men's costume in the UK, and a good mask carries it entirely. Men's scary clown costumes
2. Grim reaper. Hooded robe, skeletal hands, scythe. Warm, which matters at the end of October. Men's grim reaper costumes
3. Dracula. A proper cape and collar, not a plastic one. It's the difference between a costume and fancy dress. Men's vampire costumes
4. Skeleton suit. Print morphsuit or a tailored skeleton two-piece if you want to stay smart. Men's skeleton costumes
5. Zombie in office wear. Your own shirt and tie, distressed, plus grey makeup. Costs almost nothing. Men's zombie costumes
6. Devil in a suit. Red shirt, black suit, horns. Works if you're going somewhere with a dress code. Men's devil costumes
7. Pirate captain. Coat, boots, hat. One of the few looks that stays comfortable all night. Pirate costumes

Couples Halloween costume ideas

The rule for couples is contrast, not matching. Two people in the same costume reads as a mistake; two people in opposing versions of the same idea reads as deliberate.

1. Elphaba and Glinda. Green and pink, opposite ends of the same story. Wicked costumes
2. Vampire and hunter. One in the cape, one in the coat with a stake.
3. Angel and devil. White and red, wings and horns. Obvious, and it works every year.
4. Hero and villain. Batman and a Joker-style clown, or Superman and a rival. Batman costumes
5. Two skeletons. Matching bodysuits with different face paint. Cheap, warm, and it photographs well in low light. Skeleton costumes
6. Day of the Dead pair. Matching sugar skull makeup, one in black, one in white.
7. Ghost and medium. One draped in white, one in a fortune-teller's shawl reading their palm. Ghost costumes

Group Halloween costume ideas

Because Halloween is on a Saturday this year, group costumes are worth the coordination — there are simply more parties to wear them to. Pick a theme that scales, so a latecomer can still join.

1. The whole Addams family. Scales to six people without repeating anyone. Addams Family costumes
2. A K-pop stage line-up. Coordinated outfits in one colour story, different silhouettes each. KPop Demon Hunters costumes
3. Hogwarts houses. Four people, four colours, one shared uniform base. Harry Potter costumes
4. A superhero team. Or better, the villains they fight. Superhero costumes
5. Pirate crew. One captain, everyone else in stripes and sashes. Easy to add people to. Pirate costumes
6. A video game roster. Mario, Sonic, Minecraft — instantly recognisable across generations. Video game costumes

Kids and family Halloween costume ideas

For children, the priorities are different: it needs to go over a coat, survive a wet pavement, and not frighten anyone at the door. Check the sizing by age rather than by height, and look for a costume that layers.

1. Friendly pumpkin. The safest choice for toddlers and the warmest. Pumpkin costumes
2. Sheet ghost. The classic, and the one children like best because they can run in it. Ghost costumes
3. Spider-Man. Year after year, the most-requested boys' costume. Spider-Man costumes
4. Little witch. Hat, cape, striped tights. Layers over a jumper without looking wrong. Girls' Halloween costumes
5. Minecraft or Sonic. Recognisable to every child at the party, and comfortable to wear. Minecraft costumes
6. Matching family theme. One idea, four sizes — skeletons and pumpkins both work across ages. Baby and toddler costumes

Anime and cosplay costume ideas

Anime costumes have moved from convention halls into mainstream Halloween parties, and they have a real advantage: you can wear them again in March at a convention. If you're spending properly on one costume this year, spend it here.

1. Demon Slayer Corps uniform. The haori pattern does the recognising for you. Demon Slayer costumes
2. Nezuko. Pink kimono, bamboo, and the most recognisable silhouette in the series.
3. Gojo from Jujutsu Kaisen. The blindfold and white hair are the whole costume. Jujutsu Kaisen costumes
4. Akatsuki cloak. One garment, instantly readable, and comfortable over normal clothes. Naruto costumes
5. Straw Hat crew. Works as a group of three or a group of eight. One Piece costumes
6. Any character, with a proper wig. For anime looks the wig is more than half the costume — budget for it first. Halloween wigs
7. Super Mario. The overalls-and-cap look that everyone recognises instantly. Super Mario costumes
8. Sonic the Hedgehog. Kids' and adult sizes, and it reads from across a room. Sonic costumes

Halloween costume ideas under £20

Most people in the UK spend under £25 on Halloween, so this is the realistic bracket. The trick is to buy one strong piece and build the rest from what you own — a mask, a wig or a cape will carry an outfit that costs nothing else.

1. Mask and your own black clothes. The cheapest complete costume there is. Halloween masks

Four more that follow the same logic: a cape over a plain outfit makes a vampire; face paint alone makes a skeleton or a sugar skull; a hat or headband plus black clothes makes a witch or a devil; and tights and gloves turn an ordinary dress into a full look.

Last-minute Halloween costume ideas

If you've left it late, you have two problems: choosing and getting it delivered. Solve the second one first. Our last order date for Halloween delivery is 10 October — after that, build from accessories you can get quickly rather than a full outfit.

The fastest complete looks are the ones needing a single item: a mask, a wig, or face paint. A zombie office worker, a skeleton in black, or a ghost in a white sheet can all be assembled in an hour from a wardrobe plus one purchase.

Finishing the look

Three things separate a costume that works from one that doesn't, and none of them is the outfit itself.

The wig

More than anything else, a wig changes your silhouette, which is what people actually register from a distance. Buy the wig before you buy the dress. Browse wigs

The makeup

A £6 face paint kit does more for a photograph than a £40 costume upgrade. Test it a few days beforehand if you have sensitive skin, and buy a proper remover at the same time. Browse makeup and face paint

The props

One prop makes a costume specific — a scythe, a broom, a staff. Check the venue's rules first, as many bars won't admit anything weapon-shaped. Browse costume props
