The Long-Neck Look for the Jurassic
Is it a dinosaur? Is it a fashion-forward periscope? Nope—it’s you, absolutely thriving in this Adult Brontosaurus Costume. You've got height, you've got tail, and you've got a soft-stuffed prehistoric head sprouting from your own like it’s no big deal. Brontosaurus energy is calm, chill, and definitely the friend who shows up with snacks. Sound familiar? Exactly.
Wearing this means you’re not just showing up to the party. You’re towering above it—politely, of course.
Design & Details
This costume is made of plush polyester velour with fiberfill stuffing for the tail and dino details. The full-body jumpsuit zips up the front, making it easy to wriggle in or out between evolutionary eras (or snack breaks). A soft-sculpted tail adds some sway to your step, and the comfy fit leaves plenty of room for movement—whether you're grazing or grooving.
But the real magic? That iconic neck. The inner foam hood supports a fiber-filled brontosaurus head that rises high above your own, complete with printed eyes, a friendly face, and serious dinosaur charisma. Your own head peeks out from the base of the neck, so you’re still visible—just slightly upstaged by your prehistoric plus-one.
Dino-Mighty Look
Why blend in when you can Bronto in? This costume is funny, unexpected, and ridiculously charming—just like the ancient vegetarian it’s inspired by. From Halloween strolls to office costume contests, you’ll be the tallest tale of the night.
