My niece's 2012 Halloween costume. She was going to be a rainbow princess but then she changed her mind when she saw this pattern. Used Simplicity 1765 for the suit and made up the dinosaur egg bag on my own.
Halloween Dinosaur Costume: Be creative make the dinosaur head by using spare shoe boxes. Take 2 shoeboxes. Remove both the lids and take the remaining two boxes. Place one on top of the other with open ends closing each other. Insert one box into another just an inch or 2 on one side making a V shape. Now, this will act like the head of the dinosaur. Stick eyes on the top and teeth to the side of the box. Make a body and tail, similarly with things around in your home.
