Kids Grim Reaper Light Up Costume. Hooded robe with a mesh skull-print face covering, a detachable chain and a three-part self-assembly scythe, plus battery-operated red LED glasses (batteries not confirmed in the pack, worth having spares to hand).

Kids Glow Skeleton Morphsuit. One piece, on in seconds, with graphics printed in glow in the dark ink that charges under light and glows in the dark.

A built-in fan keeps the abduction illusion on our Kids Inflatable Red Alien Pick Me Up Costume fully puffed up for 4+ hours on 4 AA batteries (not included), and the open design leaves your child's face completely clear. One size, fits most children between 3 ft 11 in and 5 ft 3 in tall.

Want the giant T-Rex from our dinosaur range? Our Kids Inflatable T-Rex Dinosaur Costume pulls on over the head with hook-and-loop fastening at the front, and the same built-in fan keeps it inflated all day. One size fits most, 100% polyester.

For an older child who wants dressing-up plus an activity, our Kids Slime Zombie Morphsuit comes with a make-your-own glow in the dark slime kit alongside the suit itself. Sized by height in Medium (7-9yrs) and Large (10-12yrs), with the same four-way stretch fabric as every Morphsuit.

Halloween safety for kids

Every costume in this range goes through over 30 measurement checks, and every kids' product is safety tested by accredited labs before it goes on sale. Beyond that, three things matter most on the night: your child can see out of it, get in and out without help, and won't trip on the hem.

• Choose a light up or glow in the dark costume, or add one bright piece, so your child stays visible on a dark pavement.
• Pick a hem that clears the ground rather than one that trails.
• If your child will not wear anything over their face, our inflatable alien pick-me-up and the animal costumes both leave it clear.
• For younger trick-or-treaters, keep an adult close and stick to well-lit streets where you can.

Every product page shows the whole costume, so you can check fit and visibility before you buy.

Buying a Halloween costume for a child

Sizing is the main thing to get right. Our inflatable pick-me-ups are one size and fit up to roughly 5 ft 3 in, while Morphsuits and dressed costumes such as our grim reaper light-up costume are sized in age bands, and top sizes vary by style. Check the chart before you order for an older child.

Care is simple: hand wash fabric pieces in cool water, air dry flat, and sponge-wipe the inflatables. Nothing goes in a machine or a tumble dryer.

Pair a costume from this page with scary Halloween costumes for the grown-ups, or all Halloween costumes to shop for everyone. After Halloween we also do kids Christmas costumes and kids World Book Day costumes.

Kids Halloween costume questions

What makes a Halloween costume safe for a child?

Fit and visibility matter most: your child should be able to see clearly, get in and out without help, and stay visible after dark. Every costume in this range goes through over 30 measurement checks and is safety tested by accredited labs before it goes on sale, and a light up or glow in the dark style adds extra visibility for trick-or-treating.

Do you have Halloween costumes for 11 and 12 year olds?

Yes. Our inflatable pick-me-ups are one size and fit up to roughly 5 ft 3 in, so a tall eleven year old or a small twelve year old gets an easy fit. Our grim reaper light-up costume goes up to a 12 to 14 years size, but not every Morphsuit or dressed costume goes that far, so check the size chart first.

What works for a child who will not wear a mask?

Anything that leaves the face clear. The inflatable costumes, the animal costumes and the open-face outfits all work, and none of them need anything pulled over the head.

How does a glow in the dark costume work?

The graphics are printed with glow in the dark ink. It charges under light and then glows in low light or darkness, so there is nothing to switch on and no batteries to carry.

How do you keep trick-or-treating safe after dark?

Add one bright, light up or glow in the dark piece so your child stands out from the pavement, pick a hem that will not trail, and keep an adult close for younger children.
