Dinosaurs never go out of style with kids, and the inflatable T. rex turned them into one of the funniest adult costumes too. Whether you want a cute hooded stegosaurus or a giant wobbling T. rex, this one gets a reaction everywhere you go.
What Makes It Work
Decide between two very different routes. The hooded version is a jumpsuit or hoodie with a dinosaur face on the hood, spikes down the back and a stuffed tail. It’s warm, comfortable and perfect for kids.
The inflatable version is a full-body suit with a little battery fan that puffs it up into a huge dinosaur. You look out through a window in the neck. It’s ridiculous in the best way, and it’s a guaranteed photo.
Either way, the tail and the spikes sell it. For DIY, sew or glue felt triangles down the back of a green or brown hoodie and stuff a tail with fiberfill. Clawed gloves or slippers finish it.
What People Get Wrong
Inflatable suits in crowded rooms. They’re huge, you can’t see your feet well, and the fan runs on batteries that die at the worst time. Bring spares and give yourself space. For kids, a tail that drags on the ground gets stepped on all night, so pin it up a little.
Buy It or Build It?
Hooded kids’ dinosaur costumes run about $20 to $40. Inflatable adult T. rex suits run about $40 to $80. A hoodie and felt spikes makes a cheap homemade version.

FAQ
How do I make a DIY dinosaur costume?
Cut felt triangles in a contrasting color, glue or sew them in a line from the top of a hoodie’s hood down the back, and add a stuffed felt tail at the waist.
How long do inflatable costume batteries last?
Usually a few hours on fresh AA batteries. Bring a spare set if you’ll be out all evening.
Is an inflatable dinosaur costume hot?
It can be warm inside, but the fan moves air constantly, so most people find it manageable.
What's a good group dinosaur costume?
A whole herd of different dinosaurs, or a family of T. rexes in different sizes, makes a great group photo.
