Mirrored Disco Ball Halloween Costume

Step 2 Cut domes and velcro together

I decided my best option for the disco ball form would be using acrylic domes, available at many plastic supply stores. Although expensive, ($180!) and not perfectly round when seen from the side angle, they are very strong even when cut and still have flexibility. Also, I needed a solid way to attach the domes together, and get in and out of my costume, so the dome "lip" came in handy.

Using a dremel tool, (with help from my friend Dave) I cut out each dome's top and bottom to fit around my body. This step was made easier by taking rough measurements of my bust and bottom using wire shaped around my form and then sketching it on the domes.

I used industrial strength velcro (available at Home Depot) to attach the sides of the domes together. It makes an amazingly strong bond! After lining both edges I also made a velcro "hinge" on the interior of one side to make it easier to put on and take off.

I celebrated getting this far by dancing around doing the robot.
