An easy example that clothes are used for is status. Others are power, knowledge, cheek... Personally, I like trying to use clothes as a way to diffuse aggression. Being weird and slightly off - but still acceptable, because that's the kind of person I am. The kind of thing that eventually fades back away, but lingers. Something that leaves people with a positive impression but is not totally pinned down. A glance out of the corner of an eye and a smirk that you're not sure what it means. Mischievous with a little bit of playful anarchy is probably also a good way to put it.
I'm not saying I've mastered it or that it always works, but it's the direction I'm trying to head.
I, for one, appreciate the time it took to put these several posts together. Thanks; great food for thought.
