Ah, like the belly button piercing, for example. It seems that there was some video back in the 80s, during the MTV times, whose popularity instantly made that particular piercing a female-only thing forever.
To put forth an unpopular opinion, which seems to be a thing on social media at the moment, so I'll bring it here: We like to say heels were invented by men for men, and while that's technically true, nobody was wearing what I consider "real" heels until the 1950s. Even King Louis XIV, whom many people like to look to for inspiration, did not wear "real" heels. At least not in that famous painting. The Persian cavalry did not wear "real" heels, they were for utility. The point is twofold: Firstly, what we are talking about centuries ago is fundamentally a different animal than what we have today, and second, it kind of doesn't matter anyway, because they are firmly entrenched in the worldwide psyche as being feminine, and it's going to be damn near impossible to get them back.
There is one hope, though. Long hair and earrings. We did get those back from the girls, so maybe high heels are simply unlikely, rather than impossible.
