It seems to me that the bra is a vestige of antiquated patriarchal norms centered on how women should present themselves in public, rooted in the exaggerated sexualization of the female mammary gland through centuries of superstition-based, (i.e. religion-based,) narrative dictating what is appropriate. Anyway, by all means, ditch the over-the-shoulder-boulder-holder and set your tatas free. Anyone upset by it probably isn't someone you'd want to associate with anyway.
