Upvoted for your very relevant article selection.

Yes, I was aware of both the pink/blue reversal and the unbreeched boys practice. The insanely rapid (at least if considered on an evolutionary timescale) pink/blue reversal in particular indicates to me that some things are entirely culture.

I think the young Louis XV is even more apropos to illustrate the sentence you responded to from my post. In fact, I'll go add that link in now...

Still, regardless of where my preferences come from, I don't particularly want our culture to return to dressing all children in frilly little dresses. I see this as entirely consistent with my dislike of frilly little dresses. Even so, I understand that not everyone has my preferences, so my hope is to live in a society that increasingly doesn't demand that people conform to whatever the majority preference is. Rather than, say, living in a world where wearing frilly little dresses is banned for people of any gender.
