That is not the difference of binding or not binding the chest. That is literally transforming her body. Like, that wouldn't have just been uncomfortable and caused problems with breathing. Her chest would have been crushed and disfigured and not just returned to "Normal" if her boobs are THAT big but she was made THAT flat while wearing the armor "incorrectly". 😑
And why was her corset apparently sort-of correctly fitted underneath the armor? The corset would have been part of the binding, or set on top of the binding.
Imagine putting on a loose shirt, then throwing a compression shirt over it. Or more accurately, imagine puttinng on a temporary cast, then trying to force undersized armor over it. The corset wasn't tightened fabric. It was a more aolid material. 😑
This is getting weird.
I mean yes, it was already weird. But like the contrived stuff is growing and getting weirder and more nonsensical.
