Scary Halloween Costumes

Scary Halloween costumes for every taste

We stock scary Halloween costumes and fancy dress for adults and kids, from full-body Morphsuits to a light-up reaper costume, alongside plenty of lighter, funnier picks if that is more your thing.

The scary end of the range starts below. If you would rather laugh than jump, skip straight to the lighter picks further down the page.

Scary costumes and fancy dress, from full-body monsters to light-up reapers

Every design here goes through over 30 measurement checks, and we run over 500,000 quality checks across the business each year.

Our Arachnomania Morphsuit wraps you head to toe in blue with a white web print scattered with dark grey spiders, and no face on show. One size fits most, 4-way stretch fabric, double zips for getting in and out.

The Black and White Monster Morphsuit fades from black at the hood down to white at the hands and feet, with jagged linework instead of a flat split. Full face-covering hood, one size fits most.

The Kids Grim Reaper Light Up Costume is a ragged hooded robe printed with a skeleton ribcage, battery-operated LED eyes that glow red, a detachable chain and a self-assembly scythe. The eyes are the part that still works after dark. Four kids' sizes.

Not looking for scary this year?

Then start at the other end of the range. Same measurement checks, none of the fright.

Our Alien Costume Piggyback is a ride-on illusion suit that makes it look like a green alien is carrying you. Comedy over scares, one size fits most adults.

Our Womens Day of the Dead Senora Costume is a tiered satin dress with red sugar-skull-print ruffles, a flower-trimmed belt and a lace veil headband. Colourful fancy dress rather than gory, sized M to XXL.

The Kids Glitter Black Cat Dress Costume is a sparkly dress with a glittery skirt overlay, a printed cat face, an attached tail and a fur-trimmed cat-ear headband. Family-friendly fancy dress for younger trick-or-treaters, sized by age.

Buying for a younger child? Kids' costumes are sized by age rather than adult sizing, so check the age on the product page before you order from our kids Halloween costumes range. For groups, our stag and hen do costumes cover themed fancy dress, and the rest of the year sits in occasion costumes.

The decision people usually get wrong

It is easy to choose a costume on how dramatic it looks in a photo, then remember at the party that you have to wear it all night. That is exactly why we measure every design against 30+ points before it goes into production, so it still feels right hours in, on the funny costumes as much as the scary ones.

The other mistake is timing. A 2025 YouGov survey found that among people who celebrate Halloween in Britain, 57% only start planning a week before it, and just 5% plan two to three months ahead. A week is a thin window if you want a specific costume in your size.

Frequently asked questions

What if I would rather not do scary this Halloween?

Then skip the scary end of the page. Our range runs to comedy and colour as well, from a ride-on alien piggyback suit to a tiered satin Day of the Dead dress, and a Morphsuit is only one option among many.

What is included with a scary Halloween costume?

Every product page lists exactly what is in the pack, so you know before you buy. Our light-up grim reaper costume for kids, for example, ships with the hooded robe, a detachable chain, a self-assembly scythe and battery-operated LED eyes, exactly as listed. One photo on this page adds a styling extra for the shot: the Day of the Dead dress is shown with a flower bouquet, which is not part of the pack.

When should I buy my Halloween costume?

Earlier than most people do. The same 2025 YouGov survey found that 57% of British Halloween celebrators only start planning a week before. In our experience, popular sizes in scary costumes and fancy dress can sell out in the final fortnight, so ordering earlier helps.
