In the movie, The Matrix, the Lady in Red was a woman wearing a low cut, sexy red dress. The woman, if one looked at just the right angle, with one eye partly closed, could be a Marilynn Monroe double. The lady in red I saw from the grassy knoll of the planetarium was of a different ilk. She was dressed in red from head to toe, had a red umbrella, and a red purse.
At first glance, I thought she might be a Buddhist monk but the clothes were red, not saffron or brown or white. I think she was just a woman who enjoys wearing a color with the intensity of red.
