I saw all the wars about greaves and cuirasses (cuirassii? cuirassers?)
I saw a picture and then it struck me...
In Fallout: New Vegas you have mods for weapons:
for example you have a hunting rifle, all over the Mojave Wasteland you can find "Accessories" for your gun.
Like a Scope, extended magazine, or a better barrel for more precision.
Now I think there is a similar system going on in Skyrim, maybe for armor, but also for weapons.
Only instead of finding them, you create them by smithing.

(thanks Luke Skyrimmer) ?
As you can see, on the left side he has a leather "shirt" beneath the straps, studded leather flaps on his fur leg protectors, and an extra leather plate on his left shoulder.
nothing confirmed, just think about it....
