How inflatable costumes work

Most inflatable fancy dress uses a small battery-powered fan, usually clipped inside near the waist or back. It runs constantly, pushing air into the suit so it stays puffed up. Batteries are often not included, so check the listing and keep spares handy, as a flat battery means a sad, saggy dinosaur.

They’re made from thin polyester, which is light but can tear on sharp edges. Keep them away from heaters, candles and anything spiky.

Inflatable dinosaur costumes

The T-Rex is the undisputed favourite, for adults and kids alike. Ride-on styles, where it looks like you’re riding the dinosaur, are brilliant for videos. They’re also a hit for Halloween and World Book Day.

Animals and characters

Sharks, cows, horses, hippos and mice all make good group costumes. Alien abduction styles are a clever optical illusion and always get people talking.

Kids’ inflatable costumes

Smaller versions suit children who’ll love the drama. Keep an eye on younger kids, as visibility can be limited and they may trip on stairs. More ideas in our kids’ fancy dress.

Is an inflatable costume right for your event?

They’re perfect for outdoor parties, fun runs and daytime stag or hen antics. They’re less ideal in packed pubs, on public transport or anywhere you need to sit down for long. Going to a bar? Something like our men’s fancy dress or women’s fancy dress might be easier.

A good trick is to pair one inflatable with a group in simple matching outfits, like a dinosaur with a crew of safari explorers from our fancy dress hats range.

Sizing and comfort tips

Most inflatable costumes are one size, designed to fit a wide range of heights. Very tall or short people may find the legs or face window sit in an odd place, so check the height range in the listing and our costume size guide. Wear light clothes underneath and comfy trainers. For more silly ideas, browse shop by theme or see our hen and stag fancy dress.

How do inflatable costumes stay inflated?

A small battery-powered fan inside the suit runs constantly to keep it puffed up. Batteries are often sold separately, so check the listing and bring spares for a long day.

Are inflatable costumes one size fits all?

Most are one size and fit a wide range of adult heights, with separate versions for kids. Very tall or short wearers should check the height range, as the face window may not line up perfectly.

Can you sit down in an inflatable costume?

You can, but it’s awkward, and full-body styles squash easily. Ride-on designs and smaller suits are easier if you’ll need to sit for a while.

Are inflatable costumes hot to wear?

The fan pushes air around you, so they’re not as hot as you’d expect, but the material doesn’t breathe. Wear light layers and take a break now and then on a warm day.

Are inflatable dinosaur costumes good for kids?

Kids love them, and smaller sizes are made just for them. Supervise younger children, as their view is limited, and see our kids’ fancy dress for more ideas.
