Its ugly with most helmets/boots/gauntlets because there is not many armor pieces that are of a shady grey color, but it can be beautifully donned if you know which pieces to use it with
This can help.
Also there is only so few plate armours, dont remove anyone.
Since I play this game there is only 4 full plate armour : plate armour, gothic, milanese, heavy plate... Love them all like your own children!
