Win Halloween With This Adorably Fierce DIY T-Rex Dinosaur Costume

When thinking about making a dinosaur costume, one thing comes to my mind: the scene in Step Brothers when Richard Jenkins confesses to his dinosaur dream. "When I was a little boy, I always wanted to be a dinosaur. I wanted to be a Tyrannosaurus Rex more than anything in the world. I made my arms short and I roamed the backyard, I chased the neighborhood cats, I growled and I roared. Everybody knew me and was afraid of me. And one day my dad said, "Bobby, you are 17. It's time to throw childish things aside," but he didn't really say that, he said, "Stop being a dinosaur and get a job." That said, let's do this.

The key to a great T-Rex costume is to have short arms. Cut off the sleeves of a green sweatshirt, sew the arm holes closed, and then re-attach the sleeves to the front of the sweatshirt. Spray paint the sweatshirt and pants in hues of greens and browns to give the clothing a scaly texture. To create the dinosaur hat, attach a cardboard strip to a baseball cap and cover in green felt. To make your dinosaur hat really come to life, use felt to make sharp teeth and small eyes.

A dinosaur costume isn't complete without a tail! Create a long tail out of felt, stuff with fiber fill, and hot glue onto the back of a pair of pants. Use the same felt to create T-Rex shoe and hand covers — complete with sharp, pointy toe nails.

Makeup: Prep your palette by applying a full-coverage foundation to your skin. Highlight, contour, and apply blush as if you are doing your standard flawless face, except go slightly heavier on your blush and highlighter so that it really pops through the next stages of the look. Brows: For the eyes, the eyebrows are super clutch! Start off by covering your eyebrows with white or cream eyeliner — this will allow the green pigment to pop. Next, apply green face paint or a cream shadow to your eyebrows, exaggerating them to look fuller, wider, and angled by making small hair-like strokes with a fine-angled brow brush. Eyes: Add a neutral peachy color into your creases, and a cream highlighter to your brow bones and eyelids. Next, apply an elongated lime green winged liner on the inside corners of your eyes, bringing the point or the flick toward the center of the bridge of your nose and slightly under your lower lash line. Then do another elongated cat eye with a teal liner on the outer corners of your eyes. Finish with a few coats of mascara. Scales: Using a large fishnet pattern of any source, lay it over your eyes and then use a makeup sponge to stamp on either cream shadow or face paint in a gradient color scheme (the darker hue on the outside of your eyes and lighter towards the center). Connect each side of the scale mask by applying the fishnet to your nose and apply the lightest hue. Lips: To create this shimmering teal green lip, apply either a teal eyeliner or lipstick as your base and then layer on metallic green and teal shadow to give your lips dimension. Finishing touches: GLITTER! Tap it on anywhere that your heart desires! For this look, we applied glitter to the outside corners of her eyes, her temples and her upper cheekbones.

To create this look, you'll want to cut a huge head out of foam core and cover it in felt. Leave a hole in the center that is the perfect size for your head — too large will mean the dinosaur head will fall off and too small will mean headaches for the whole night. Create a tail out of the same felt, stuff with fiber fill, and attach onto the back of a pair of shorts.

Getting that perfect dinosaur walk down is a must.

But let's be real: That T-Rex would eat that other cute little herbivorous dinosaur in one second. (Sorry, Sean!)
