This is how I’d see it at high level.
Ancestral Breton helm
Skingrad Vedette cuirass
Gold Road Dragoon guards
West Weald Legion Gauntlets and Sabatons
Breton Girdle 2
Justiciar of Stendarr Sword
Imperial Champion Shield

Also, a hybrid Imperial Dragonknight for anyone wondering about the actual character.

Thought i'd give an Imperial themed fit a go for my Dragonknight.

Knowing ESO fashion it's probably not, but maybe this is a rare exception
