If you want to transform into warrior princess, you’ve got to put in a lot of work – it’s only appropriate. Instructables user Carleyy put more than enough time and labor in to become Xena. A few skills come in handy for this costume including clay molding, sewing, and being able to work with leather. You don’t have to know how to use a chakram, but it doesn’t hurt. Of all the pieces from the boots to the corset, the breast plate armor looks to be the trickiest. She made it from latex and broke the process down as follows:
Design armor by drawing out on paper/cardboard how you want the breast plate to look. This will just be the 2D design.
Mold clay into the 3D design of the breast plate. Spray the clay mold with a parting agent. This will let the clay separate from the plaster.
Pour the plaster over the clay model. Follow instructions for mixing the plaster. Make sure to build a wall around our mold before you pour so the plaster doesn’t run everywhere. Once the plaster dries remove the clay from the plaster. I had to use a toothbrush to get some of the clay out.
Fill the negative plaster mold with liquid latex. I painted it in with a paint brush.
