So my sister is a religious sister: she wears the same thing every day (habit and veil). When you see her and you know "Catholic code", you immediately know her community, her discipline and probably something about the type of work she does. Pretty much everyone can read "religious woman set apart" which deeply changes how people interact with her. Is this presentation virtuous simplicity or self righteous?

I guess it matters to me what you are presenting and why. Presentation is incredibly powerful, and the lack of awareness of how we present baffles me.
