Collection: Dinosaur Costumes

Dinosaur costumes range from full inflatable T-Rex suits to simple spiked hoodies, and most looks build from one recognisable piece rather than a full head-to-toe outfit. Start with the body suit or hoodie, then add claws or a tail if you want the fuller effect. They work equally well for kids Halloween costumes and adult party wear, since the shape reads instantly at any size.

Dinosaur costumes for kids

An inflatable T-Rex or a spiked hoodie is one of the easiest wins for a school event or Halloween party, because the shape is recognisable from across the room and needs no accessories. Younger children often prefer the soft hoodie version, since the full inflatable suit can be bulky for very small kids. Browse our wider kids Halloween costumes for more low-effort options.

Adult and inflatable dinosaur suits

Adult inflatable dinosaur suits are a reliable crowd-pleaser at fancy dress parties and stag or hen nights, since one costume gets attention without any extra styling. They pack down small for travel but need a bit of room to move once inflated, so check the fit guide before ordering. Pair the look with other group fancy dress ideas for a themed night out.

Building a dinosaur group or family look

A family or group of dinosaurs works well because every costume follows the same simple shape, just in different sizes and colours. Mix a T-Rex with a stegosaurus or triceratops style for variety within the theme. It also suits a toddler costume alongside older siblings without anyone standing out as underdressed.
