Crystals: I started off by drawing on my plaster headcast to figure out how many pieces I needed and what they should be shaped like. I wanted the diamond transformation to stretch down my neck and shoulder. Then I sprayed a mold release on the cast and painted thin latex on in multiple layers. After letting that dry, I individually glued over 1000 Swarovski crystals onto the pieces with E-6000. The bond was great, and made the prosthetic pieces stronger. The headcast ensured that each piece was formed perfectly to my face shape, neckline, shoulder line and clavicle. The prosthetics were glued onto me via ProsAide and held on amazingly for 12 hours, even with me smiling, talking, eating and fidgeting. I specifically chose to make latex pieces instead of gluing stones over a mesh so that I could re-use the pieces over and over again and have full range of motion each time I wore this costume. I also don't have time at cons to glue 1000+ crystals to myself each time, but I do have time to glue a few pieces on, then scatter more crystals around them for a blended look.
