Dinosaur Land

Stomp, roar, repeat. Dinosaur Land is the Jurassic corner of the Costume Galaxy, with 10 dinosaur costume ideas for every age — from a baby in soft spikes to a full T. rex built out of a cardboard box. Most of these are genuinely simple builds: paint, a box, and a grown-up with scissors get you most of the way there, and every guide says exactly what to buy versus what you probably own already. If your kid has watched the same dinosaur movie forty times, start here. The flagship Baby Dino is the crowd favorite for a reason. Every costume below links to a free step-by-step build guide with honest time and cost.
