Bodysuit for a Batgirl costume, the rest of the costume was not made by myself.
The fabric is a metallic print nylon lycra and required much work to find the right combination of needle, thread and sewing machine to sew up. However once this was found sewing commenced easily and went quickly.
The suit required a few extra seams from the standard four panel body suit, which was easily created by cutting at the waist seam then adding tucks from bust point to waist to simulate darting which was seen in the original.
It closes up the back with a long purple invisible zip and I had found the easiest way to insert one of these was to use a piping foot. It means you have control over how close the seam gets to the teeth by opening the teeth up and getting the needle right up to the edge. Of course now that I found a better foot, it is even easier.
The original was made from stretch lame apparently and it is still possible to buy.
