Kids Dinosaur Costumes

Kids Dinosaur Costumes, From a Toddler Jumpsuit to an Inflatable T-Rex

Kids' dinosaur costumes here come in two formats: a jumpsuit you pull on, or a suit that inflates around your child on a battery fan. We stock five styles: two jumpsuits, two inflatables, and a piggyback illusion, sized from 1 year old up to a 5'3" height band for older children.

Dino onesie, T-Rex suit, dinosaur fancy dress: the names vary and the range below covers all of them. These get worn at Halloween, on World Book Day, and during school dinosaur topic weeks.

Choosing Between a Jumpsuit and an Inflatable Dinosaur Costume

The two formats suit different days. A jumpsuit goes on over what your child is already wearing, has nothing to switch on, and stays comfortable through a full school day. An inflatable or ride-on costume is the one for a party or a trick-or-treat round: it blows up well past your child's own outline on a built-in fan, runs on 4 x AA batteries (not included), and holds its shape for 4 or more hours.

We would rather you didn't have to guess at the size chart, so every costume goes through over 30 measurement checks. All of our kids' products are safety tested by accredited labs.

The Kids Inflatable T-Rex Dinosaur Costume is the classic blow-up dinosaur: one piece to pull on, a built-in fan running on 4 x AA batteries (not included), and one size that fits most children.

Toddlers get their own version. The Kids Green Dinosaur Costume is a green jumpsuit with an orange spotted print, an attached hood and a velcro-release tail, in Small (1-2 years) and Large (3-4 years).

Some days riding one beats being one. The Kids Ride On T-Rex Skeleton Inflatable Costume creates the illusion of your child riding astride a skeleton T-Rex, staying inflated for 4+ hours on its built-in fan and battery pack, in one size that fits most ages.

Nothing to switch on and no batteries to lose: the Kids Orange T-Rex Dinosaur Costume is an embossed velour jumpsuit with an attached tail and feet plus a detachable headpiece, for ages 3 and above in sizes 3-4, S, and M.

Turn the joke the other way round and the Kids T-Rex Piggyback Costume self-stuffs in about a minute into an optical illusion of your child being carried by a dinosaur, fitting heights from 3'11" to 5'3".

If your child's heart is set on a different creature entirely, our wider kids' animal costumes range runs from farmyard to jungle, and the rest of our kids' costume themes sit one level up.

Frequently Asked Questions

What age do your kids' dinosaur costumes fit?

It varies by style: our toddler jumpsuit runs Small (1-2 years) to Large (3-4 years), the velour jumpsuit covers ages 3 and up in sizes 3-4, S, and M, and the two inflatable costumes are one size that fits most children. The piggyback costume is sized by height rather than age, 3'11" to 5'3", so it's worth measuring your child against that range before ordering.

Do the inflatable dinosaur costumes need batteries?

Yes. Both the inflatable T-Rex and the ride-on skeleton version run on a built-in fan powered by 4 x AA batteries, which aren't included, and stay inflated for 4 or more hours once switched on.

Can my child see and breathe properly in an inflatable dinosaur costume?

Yes. The inflated body sits out in front of your child, so they can't easily see their own feet or much to the side, which is worth walking through with them after dark and pairing with something reflective if they're near traffic. The fan runs the whole time to keep the suit inflated, so there's air moving through it rather than sealed in.

What's the difference between a dinosaur jumpsuit and an inflatable dinosaur costume?

A jumpsuit is a close-fitting one-piece with no batteries and no fan, so it can be sat down in at a desk for a whole school day. An inflatable costume blows up well past your child's own outline on a battery-powered fan, which is better suited to a party or a trick-or-treat round than a classroom. Both go on in one piece.

Is a dinosaur costume suitable for World Book Day as well as Halloween?

Yes. The jumpsuit styles in particular suit a school dinosaur topic week or World Book Day just as well as they suit trick-or-treating, since there's no scary print to tone down for daytime wear.

How do I wash a kids' dinosaur costume?

Give it a cold hand wash and let it air dry. Never machine wash or tumble dry, and remove the battery pack and fan unit first on either inflatable style before any cleaning.
