Did the Romans have parade armour?

[Urselius]

One definite piece of Roman parade armour - if helmets count - the toupha. This was a jewelled helmet with a crest of peacock feathers worn by later emperors in their role as conquering general. It was worn by Justinian the Great on the now lost equestrian statue in Constantinople. An early version is worn by Constantine the Great on a coin (the one on the dustjacket of Southern and Dixon's 'Late Roman Army').
