Yeah, it’s like Fallout 3’s clothing and armor:
clothing/armor -> legs, arms, and torso
hats/helmets -> head
(except i’m not sure what they are doing with boots. if they have individually equiped boots as a peice of armor, then wouldn’t they do gloves/gauntlets too?)
In Skyrim, i’d imagine robes, animal hides, and chain/platemail as full body peices. And various hoods, fur hats, and helmets as the head piece, just like in FO3.
EDIT: According to a gameplay demo, boots and gauntlets ARE confirmed and included. So 4 different pieces of armor to mismatch and whatnot, which i’m gonna guess, rings and amulets to also wear like in oblivion.
