A cavewoman costume can be made by using a pair of scissors to alter the shape and design of an oversized yellow or brown T-shirt. A bone or primitive-looking tool may be carried to help complete the outfit.
The sleeves, hem, neck and waist of the T-shirt all need to be cut so that they have a rough, jagged look to them. If a one-shoulder look is desired, the T-shirt needs to be cut diagonally across the chest to remove the other shoulder. A black permanent marker is used to draw leopard spots or other animal markings on the costume, and a string or cord in a coordinating color is tied around the waist to create a belt.
