Chainmail + Breastplate combination?

[Watchman]

Huh. Pretty sure I've read the Romans at least fixed them on some kind... don't remember now actually... under the armour. Practical experiments apparently suggest fixing them to the body armour itself doesn't really work very well - the two need to be able to move relative to each other, or somesuch.
Though that may have been with mail; more solid stuff (like the tube-and-yoke organic cuirasses) might well provide a better "base"...

...should probably go and reread that text so I don't need to spam caveats...

In the Hellenistic world, all evidence points to the pteruges being an intrinsic part of the cuirass, whether it was organic or metal.

I'll give you the more "solid" base of the tube-and-yoke corselet and the bronze breastplate in all likelihood gives a rather better fit than the mail the Romans mostly played with.

Submallis, I may have put in too many "L"s.

Yes, though the under-garment is a matter of contention, whether or not legionaries always wore one is a particularly contentious question.
