The costume design seems to indicate some sort of Roman insignia or crest, in gold, set on a silver background. But the details are loose enough to allow various interpretations. Most common is a “flower” circle or oval with decorations on the inside, or around it. Another common motif is a lion’s head. It varies if the armour is a gold/silver combo, or just golden/brassy. It’s held up by black decorated straps over a green tunic.
