I like the leather look myself...ohne helm.
Exactly like what my character looks like.
I leveled my blacksmithing (and alchemy and enchanting), just so I could upgrade my leather set to armor values to the cap. So that I don't regret wearing glass or dragonscale armor. Maybe getting such a high armor rating wasn't even necessary. (I try to make sure my enchants don't break the fun).
I use a "hide helmet" addon.
Most armors look way too bulky. Leather looks best. Maybe also because I've been a rogue for many many years. And leather just feels best. I also used 2 swords for that many years (and axes later. bleh, ugly axes). In Skyrim however using a 2nd sword it too painful. You can't use a keybind to equip it quickly. And at lower levels, I really needed a shield to survive. But now that I am over lvl50, and now that I have my "endgame" upgraded leather set, I started using dual-wield. I feel like the rogue I've always been !
