Make it a family group costume
The ultimate Jurassic Park group look: one parent as a park ranger or Dr. Grant, another as Dr. Sattler, and the kids as raptors and a T-Rex. It’s instantly recognizable and photographs beautifully. Buy early — inflatable suits sell out every October.
Sizing & buying tips
Costume sizes rarely match everyday clothing — always check the brand’s size chart against chest, height and age. Inflatable suits need batteries (usually 4× AA) to keep inflated, so grab spares. And order by early October: Jurassic Park costumes are seasonal best-sellers and popular sizes disappear fast.
Costume FAQs
Are inflatable T-Rex costumes one size fits all?
Most adult versions are designed for a broad height range (roughly 64–74 inches). Check each listing — some are unisex one-size, others come in specific sizes.
What batteries do inflatable costumes need?
Typically 4× AA batteries (sometimes with a USB power-bank option). Batteries are usually not included, so buy them separately.
What’s a good easy Jurassic Park costume?
A park ranger or wrangler vest over your own khakis and a logo tee is the simplest, most affordable option — and it’s instantly recognizable.
