Here's one example. Lydia and me:

Plate armor with leather boots and thieves guild gloves (with an added black trim, wolf cloak, of course). It just seems to go so well together. Actually, a lot of the armors seem to go well with leather boots/bracers. Steel, elven, even glass.
Let's see some of yours?
