Aside from men being horny in the 1800s, and this being a holdover since that time, is there any actual reason why this hasn’t changed?
If society was dominated by women, would this be more likely to change?
I was sweating my ass off hiking in the hot sun, and the question has been bothering me all day after my top soaked through with sweat.
Iirc, the law specifies exposure of the female nipple and areola as the things that are indecent…
So… get some titty tassels with a large enough sticker plate to completely cover your areola, and you’re 100% legal!
 
You may consider also carrying a taser.
