It's quite a useful reminder of how norms change and aren't really norms at all (bit OT)
Another "oldie" (huh!) here. The current weird modesty about always having to wear a bra is so so hyocritical & contradictory, because most bras nowadays (that one "has" to wear) are push-up or padded. There is, as someone sad upthread, a huge acceptance of breast enlargement (now if we're talking about inappropriate let's start there).
Yet there's also a fashion for wearing leggings with thongs, so buttocks are pretty visible, or wearing visible underwear, baring midriffs, and so on.
So why the prudishness about nipples? They're just nipples.
Yet again, women negatively judging other women's bodies. Why do you think women do this? In whose interests is it for women to police other women, judge them, and moralise about them?
Think about it OP and others who are judging women's bodies & behviours like this.
Post-feminist age? Pah! don't make me laugh
