How to make a T-Rex costume

Updated February 21, 2017

You can become the king of the dinosaurs by making your own T-Rex fancy dress costume. This terrifying T-Rex outfit can double as a Godzilla costume for Halloween or any party with a horror or film them. Create a great-looking T-Rex costume in less than an hour.

Make the T-Rex's head

Form the skull from a cardboard box. Use masking tape to hold the upper jaw and lower jaw together. The jaw will be made of a 5 cm (2 inch) wide strip of cardboard. Tape these together so the mouth is open slightly or go for the wide, growling jaw.

Tape a strip of cardboard to the centre of the top-jaw piece. This is the nose. Use 2.5 cm (1 inch) wide strips of cardboard to make the shape of the T-Rex's head and the back of his skull.

Now it's time for the papier mache. Mix the water, flour and a little salt to make the papier mache glue mix. Place it in a large bowl.

Cut the newspaper into 5 cm (2 inch) wide pieces. Dip the pieces into the papier mache. Apply them to the skull to make the head of the T-Rex. Allow the papier mache to dry completely.

Roll two small balls of papier mache for the eyes. Cut out small triangles from your extra cardboard for the teeth.

Paint the head green. Paint the eyes and teeth white. Include a black pupil on each eye.

Line the inside, back part of the skull with the egg shell foam so it fits snugly to the back of the wearer's head.

Hot glue the eyes and teeth into the head.

Make the T-Rex's body and tail

Measure the wearer's hands. Cut out two pieces of green material for the right hand and two pieces for the left hand. Attach the two right-hand pieces together with hot glue to make a glove. Be careful to only glue around the seam and to leave an opening for the hand to get into the glove. Repeat the process for the left hand.

Form the tail with the rest of the fabric. Make a green cone shape out of the fabric. Hot glue the seam along the length of the tail to seal the cone in place. Fill the tail with newspapers to make it stiff.

Safety pin the tail on to the seat of the dinosaur lover's jogging bottoms.

Tip

Add LED lights to create eyes. Buy lights powered with a 9-volt battery.

Wear the green sweatshirt, jogging bottoms, head and gloves together to make the costume.
