Funny enough, that post does link a set of armor that has a place for her boobs, as it should. Because if it doesn't, it's either going to press them into your chest - creating problems, or it's going to be loose around your stomach - creating problems. It doesn't have the indent in the middle, but it does have a protruding section for her chest. But then with the dent in the middle, you're just getting into artistic freedom. (Because kratos from god of war has totally battle-ready armor)
