Those seam lines are where we broke up the pattern to make it easier to shape, and it seriously helps. What are they called that doesn’t sound completely silly?) This is also with the boob cups added in. The photo above shows Mario pushing together two pieces we didn’t make them overlap at all, if you heat up the worbla and push the two pieces together, they’re strong. One layer worked just fine for us, though. We only did one layer of worbla over a layer of craft foam, but if you’ve got the money to use two, then two layers is doubly strong. It was taped together to make sure it looked okay and fit my dress form, and underneath you can see the beginning of my skirt being patterned out. This looks like crap right now but I promise once it’s all together it looks awesome. We did the same thing to make the corset. We actually avoided the areas where my boobs are, though, so that we could shape the worbla in there correctly.
The pattern for the breastplate was made by wrapping my upper torso (and over my shoulders) with saran wrap and then with tape. A note about forming worbla over things: Make sure it’s at least double thick, because worbla will tear if it’s stretched too much. The breastplate consists of four separate pieces that were seamed together with the worbla to make the shape that goes around me, and the boob parts were made by forming the worbla over a large plastic dome (well, pick one according to your shape, since you don’t want it to look really weird). Here’s what the pattern looked like once it was cut out and put on foam. I really liked how the stomach part, kind of shaped like a corset, looked like a separate part and tucked under the top part of the chest plate, so Mario and I drew out the patterns based on that:
