"My apologies watchman". How about when your walking naked? In Morrowind they would comment if you went about naked. In Daggerfall people would respect you more differing from the value of your apparel.
In Oblivion when your in the prison, when I got out of the cave, he would say "It's that prisoner again, kill him! He might be working with the assassins!" when I was wearing a Mythic Dawn robe and hood. Their first reaction should have been to kill me. But they don't...
I would really like things to change depending on what you wear.
