Rhonda, I agree that appearance is part of the equation. But I would argue that the proportionality you reference is not what you link. Maybe a log scale is more appropriate but certainly not a straight slope. I don't pass. I also don't stick out. If I was 6'5" I would be noticed more quickly, but at 5'7" and 150 lbs, I am noticed later. The bottom line is that I AM noticed. THAT'S where dressing for the time, location, venue, etc... is important, I think.
