Nah. Those pieces of armor have a tight embrace on her boobs. And there is an even tighter embrace caused by the lack of space between her boobs. So the armor is pressing them together while holding them up with its claw-like hands. This is a very effective method for keeping your boobs from flying everywhere

So they can't fall out at the bottom or bounce out of the top or the sides.

And because of the embrace, they can't fly out of the middle. There is simply not enough space.
