This breastplate is scaled to a medium to larger busted lady. You can adjust the overall circumference around yourself by adding different length strapping or cutting the foam down to suit your liking. Every piece should be heat formed just a smidge to get the nicer curved effect. Make SURE to line up all registration key marks to each other even if it involves forcing the foam. This is what helps you achieve that super organic dome cup. This could be tricky do not get discouraged I've made many foam cups before getting it just right. I only used hand tools like a cutting knife and a heat gun. I would normally use a rotary tool on all the detail bits but I chose to do it the most basic way possible to show you just how fast and easily you can throw it together! You can also set your scale down 10% or so on your printing optionsto adjust sizing if you are a tiny lady :) Print in portrait. Landscape produces a whole new size. Foam used in my sample is from TnT Cosplay Supply.
