When it comes to including gathered gear in one's desc, I agree, it's out of place. However, a personal item that isn't something gathered in the game seems fine, like a signet ring or fancy cloak pin. Mentioning personal or favored colors for clothes might be stretching it a little, but I can see it being made to work. What about something questionable but workable like an emblazoned shield? I once put a heraldic crest on my healer's shield, with the angle that I painted each shield as I got it. At this point, it's questionable by what you've said, but most people would still find it to be fine.

You don't like the inclusion of the plate, cape, and blade, but you're fine with a mention of Jay Leno? The man doesn't exist inside the game.
