Homemade Dinosaur Costume: Easy Hoodie DIY Steps
How to make a homemade dinosaur costume?
A homemade dinosaur costume can be simple, comfortable, and surprisingly durable if you start with a soft base and add lightweight “dino” details. The easiest approach is to build on a hoodie (or sweatshirt) and matching pants/leggings, then attach spikes and a tail using felt or fleece.
1) Pick a comfy base (and a dino “color story”)
Choose a plain hoodie plus pants in green, teal, or gray for a classic dinosaur look. Size up if you want room for layers or if the costume will be worn over thicker clothing. Wash and dry everything first so nothing shrinks after you’ve attached parts.
2) Make spikes that stand up
Cut a row of triangle spikes from felt or fleece (about 3–5 inches tall for kids; adjust for adults). For a more 3D look, cut two sets of triangles, sew them together, then lightly stuff each spike with polyfill before closing. Keep spikes soft—stiff materials can poke and make the costume uncomfortable.
3) Attach the spikes down the back
Pin the spikes from the top of the hood, down the center back, and onto the waistband area. Sew with a zigzag stitch (or hand-stitch with a tight whipstitch). If you’re using hot glue, apply it sparingly and reinforce stress points with a few stitches so spikes don’t peel off mid-wear.
4) Add a tail that won’t droop
Create a tail from two tail-shaped fabric pieces sewn right-sides together, then turn and stuff lightly. Stitch the tail to the back of the hoodie or to a fabric belt that can be worn around the waist. A belt attachment helps the tail move naturally and keeps it from pulling the hoodie backward.
5) Finish with quick details
Add felt “scales” on the sleeves, simple claws on gloves, or a belly patch on the front. Keep everything flexible and avoid heavy embellishments so the costume stays easy to wear and wash.

FAQ
How do you make dinosaur spikes stay up?
Sew two layers of felt or fleece together for each spike and add a small amount of stuffing. Secure the spike bases with strong stitching (not just glue) so they keep their shape and don’t flop over.
