Only if you're actually a nord. Some Portuguese, English, Irish, Italian, American, etc. fuckwit wearing that is not effay and equivalent to a black person wearing an anubis necklace. Sheer cosplay.
It depends 100% upon who you are, OP. I can think of people it would look great on, but you have to harshly stamp out your imagination while you try to objectively determine if you're one of them. Personally, I think it would work best, if it works at all, with some simple, plain, austere clothing. I would avoid branding and logos and band tees and goofy shit like that. Try it with Nazi-esque black clothing; it might look cool.
