The Male outfit for the Forsworn is as revealing as legally possible. Really I think most of the outfits in Skyrim are ridiculous, they just don't cover enough of the body to make sense in a coldweather environment.
Bare male chests are illegal now? There are fur armours that are bare-chested, so I don't understand why Bethesda couldn't have done it for the Forsworn, if they did intend for them to be primitive. The only reason I can think of is that they created the fur armours before the Forsworn ones, they didn't want to make the two look too similar, and they didn't want to or didn't have time to return to the fur armours and make them more visually distinct. So they compromised and just made the male Forsworn armour look different, even though it doesn't fit.
It's good you made the distinction between Armor and Armour... we all know which one is correct though.

Shhh.

Yeah but a 200kg over weight beast of a man, could take out some weasly well toned block quite easily. I still say it was based on dominance for males.
Don't want to derail the thread but... Dominance comes in many forms. For the hoi polloi, 'dominance' meant physical dominance, because that is the kind of dominance that will get you resources. For the upper classes, 'dominance' meant social or financial dominance, because that is what maintains the resources the upper classes already have. And if one of the hoi polloi decides to fisticuff with one of the elite, he'll find himself in jail, or killed by lackeys, or exiled, or his family will be murdered, or...
These distinctions still hold true today, though to a lesser and lesser degree because of advances in technology, which mean that the big earners from here on out are going to be smart people and not strong people.
To get back to clothing: this was reflected in the (visual) utility of attire, which showed off potential mates' best assets. The hoi polloi showed off their bodies, and the elite showed off their wealth.
