I have racked my brains to work out what to use for the rib-cage feature on the front of the carapace armour. There are quite a few tutorials online on how to make something like that, but I wasn’t too happy going down that route.
I did find a great latex one for sale on the web, but nowhere seemed to be in stock and it looked like the manufacturer no longer produced it. But I eventually found one for sale and here it is.
I’m unsure about the colour scheme on it, my inspiration for the costume – the painted figure in another post – has the rib-cage (and face-mask) as white. Maybe that’s the way ahead?
