Did the Romans have parade armour?

[Sean Manning]

I think I remember reading someone who claimed that outdated armour in Roman art sometimes reflected objects which civilians owned for parades, theatre props, hunting, etc.

I remember an example of a probable senior officer's helmet, with a bronze leafy crown element, that looked highly unlikely for field use.

Although medieval and renaissance people were happy to wear fire-gilded armour, armour covered in gold leaf, elaborately etched armour, armour covered in the most expensive cloth available, etc. in battle and tournament. So one can't assume that just because something had expensive and fragile decoration, nobody would have worn it into battle.
