I like the look of glass (on the light side) and elven except for the helmets. I like ebony and steel and find dragon decent looking. For a Nord I would think iron, steel, blades steel, and draconic would all be good choices. Dwemer looks a little clunky to me but it's all right. If you're not smithing and making your own armor and you are going heavy, the blades armor you get on the main quest is a great choice. Good looking and good stats.
