What I am looking for is to give some more focus to what you are wearing and when. Of course you should not be forced to have a wardrobe for each situation if that is not your play style. But if you are in to that you should get something for it.
One way would be to have a kind of set bonus in the same way as for amour also for normal cloth. For example if you have the newest and most expensive fashion in the city it should give a bonus to diplomacy and can generate some more conversation options with some characters. The same would go if you look like a trader when you haggle or a blacksmith at the smith.
A cloak that shows that you are a captain of the city guard would give a bonus to intimidation in some situation and with some characters.
If you are dressed in rags and walks in to a noble house they should comment your clothing. They might not even want to address you, without using a skill as diplomacy or intimidation to get their attention.
I would also love to see a reputation system that is connected to an alias. What I mean is that you can choose to call yourself something else than your character’s real name. This means that you can create one alias that might be a famous villain and another alias that is a loved hero. Your skills in subterfuge and disguises for example would see if you get away with it. Otherwise you get found out and you get famous as being a fraud, and both aliases are ruined or merged.
