You can create a Batgirl costume for Halloween, parties, conventions or just for fun. The comic book character Batgirl, the female crime-fighting counterpart to Batman, wears the same black and yellow colours as Batman. Wearing a skirt, top, cape and boots, you can pair up with someone dressing as Batman or another character from the comics to create a theme.
Draw the bat from the Batman logo on the black piece of felt, about 10 cm (4 inches) wide. You can use the image next to this text as a reference.
Cut the black felt along the lines. Keep the bat and discard the rest of the felt.
Glue the bat to the yellow felt. Let it dry for about half an hour before going on with the next step.
Draw an oval around the logo, on the yellow piece of felt, about 1 cm (1/2-inch) following the contour of the bat's wings.
Cut out the oval and discard the remaining yellow felt.
Lay the shirt or leotard on a flat surface.
Place a thin sheet of cardboard inside of it. Make sure that the seams align at the sides and that the fabric on the front is not wrinkled or skewed in any direction.
Glue the yellow oval, with the logo attached, to the front of the shirt. It should sit over the chest. While it dries, you can carry on with the belt.
Cut off a piece of yellow tape the length of the belt.
Place one end of the tape on the end of the belt. Wrap the tape around the belt. If necessary, use another piece of tape.
Poke through the tape that covers the belt holes with a nail.
The rest of the costume does not require any additional cutting or glueing. Put on your Batman-mask, tights, skirt, boots and cape, and you should be set to go.
