As much as people make fun of boob plate, there are ways to make them perfectly viable without sacrificing much.
And from what I can see it doesn't look like the armour would be a problem to use as the chest is well designed and doesn't look to be too big to become a hindrance...
It's basically the equivalent of abbs on a chest plate like the Romans had.
Or a codpiece on medical knight armours.
None of them was actually useful and actively made the armour worse in some ways, but the downside was usually negligible so people did it anyway for bonus style points.
When it comes to the boob plate, as long as there isn't a cleavage between the boobs that would make it easier for a sword to land in the centre of the chest.
Or it's too big ( usually the width is the problem ) that it becomes a problem when swinging the sword around, a boob plate is perfectly viable.
It clearly has the look of a ceremonial armour, and a plain one would have been better for protection.
But magic most likely makes the slight differences more or less unimportant with how the magic embroideries work.
All in all, both her old and new version of the armour is perfectly fine unlike those insane skim armours that leave your belly unprotected and whatnot.
But then again," Red Sonya´s law of skimp" is also a thing so... who am I to say how magic armour works.
