So the psychic paper also acts as a perception filter? Clothing isn't the only problem that would stir a crowd though. The doctor could usually take charge with little opposition. (with a few exceptions)

Also, the clothes seem unimportant due to the current situation, like in tooth and claw. There was a werewolf running through the house, I doubt they cared about the Doctor and Roses clothes.

In the episodes set in the future, all the fashion is a bit more neutral and accepting, but this is the opposite in historical episodes, as clothes was just as much a social uniform, than cloth round the body. I think the lack of questioning is because of the unsaid authority and dominance the Doctor brings to situations.
