But how can you possibly know how many people notice (and possibly judge) you @OwlBeThere ? How do you read the minds of passers by? You're talking about people responding to you, paying you attention, or not. Those are actions. Noticing and judging are thoughts.
You keep talking about your motivation. But that's invisible and irrelevant to others' observation and judgement of you. Strangers cannot read your mind. They only know what they see. They form their own opinions about that.
I completely understand that you don't want attention and that you've found a form of self-presentation that serves to moderate other people's responses to you, reducing unwanted types of attention. That's great.
But everything you've written has been about manging people's responses towards you, their actions, by presenting them with things to notice about you, that you deem acceptable things for them to notice.
Through your actions you have successfully moderated other peoples' actions.
People's thoughts though, are their own. For all you know, far more people notice you and form opinions about you, than they would if you dressed more blandly. They just don't tell you.
It comes back to the adage that other people's opinions of you are none of your business. (And the obverse of that; your opinions and motivations are no business, or particular interest, of other people).
Which is why OP had to ask people whether they judge. She cannot tell from the actions of the vast majority of people, who've never interacted with her, and she cannot read minds.
