Dinosaur Costumes for Adults and Kids

Dinosaur Costumes for Every Age

We stock dinosaur costumes and fancy dress in three styles: full-body inflatables, a skeleton-effect inflatable, and a fleece onesie, plus kids' costumes sized from age one to nine. An inflatable dinosaur costume runs on a battery-powered fan built into the suit, keeping the whole body firm for hours instead of needing air blown in by mouth.

A good inflatable dinosaur costume comes down to two things: a fan and battery pack that keep it standing all evening, and a front opening so you can see and talk normally. These sit alongside our animal costumes and skeleton costumes in the wider costume themes range.

The Inflatable T-Rex Dinosaur Costume takes four AA batteries and holds its shape for four hours or more, with the jaw open above your own face rather than a cellophane window sealed over it.

Adult and Kids' Dinosaur Costumes

Past the T-Rex, the range runs to a long-necked Diplodocus skeleton and a fleece onesie for anyone who would rather skip the fan. Our kids' dinosaur costumes range carries more styles and sizes for children.

Prefer bones to scales? The Inflatable Dinosaur Skeleton Diplodocus Costume trades the T-Rex bulk for a long neck and a skeleton finish, lit by a built-in light unit and held up by its own fan.

The Mens Green Dinosaur Onesie Costume drops the fan and battery pack altogether: soft fleece, a hooded head with felt teeth, a trailing spiked tail, and Velcro up the front rather than a zip.

Same idea in a child's size: the Kids Inflatable T-Rex Dinosaur Costume pulls on over the head with hook-and-loop fastening, runs on its own battery pack, and comes in one size that fits most children.

For age one to four, the Kids Green Dinosaur Costume is a full-body jumpsuit with an attached hood and a Velcro-release tail, and no inflatable parts at all.

How the Fan and Battery Pack Work

Other companies' inflatable costumes typically seal the wearer behind a cellophane window: you can't talk or drink, it steams up, you overheat, and the costume comes off before the party has started. We developed inflation with the head left free, without losing the look, so your own face stays open at the front, and it stays on all night.

Every costume goes through over 30 measurement checks, and all kids' products are safety tested by accredited labs. None of the inflatable styles here suit children under three, because of the small parts in the fan and battery unit; the jumpsuit-style Kids Green Dinosaur Costume above suits a younger dinosaur fan instead.

Frequently Asked Questions

What age is an inflatable dinosaur costume suitable for?

We stock inflatable dinosaur costumes in both adult and kids' sizes, but none of them are suitable for children under three because of the small parts in the fan and battery unit. For a younger child, the Kids Green Dinosaur Costume is a jumpsuit with no loose parts, sized from around age one.

How does an inflatable dinosaur costume stay inflated?

A small fan built into the suit runs on four AA batteries and holds the dinosaur firm continuously, rather than being blown up once by mouth. On the adult styles it runs for four hours or more; runtime isn't stated for the kids' version.

Can you see and breathe properly in an inflatable dinosaur costume?

Yes. Our inflatable dinosaur costumes leave your own face open at the front rather than sealing you behind a cellophane window, so sight stays close to normal. Vision softens a little at the edges of the head shape, so take care around kerbs, steps or low light, as with any oversized costume head.

What size is an inflatable dinosaur costume?

The adult inflatable styles are one size, designed to fit most adults; the kids' inflatable T-Rex is one size too, fitting most children. The fleece onesie is sized Medium to XL for adults, and the kids' costumes run by age, from around one year old up to age nine.

Should I get a T-Rex, a skeleton dinosaur, or a onesie?

Go inflatable, T-Rex or Diplodocus skeleton, for the size and reaction that comes with it at a party, a stag or hen do, or a night out. The fleece onesie suits an adult who would rather skip the battery pack; for a young child, a jumpsuit-style costume needs no battery either.

What's included with a dinosaur costume?

The inflatable costumes come with the suit and its built-in fan and battery pack; the adult T-Rex also includes gloves, and the Diplodocus skeleton adds a built-in light unit. The fleece onesie and the kids' jumpsuit costumes are just the one-piece costume, with the hood and tail already attached.
