X post. I dunno really - Ds has been invited to a few supposed 'girly' things - jewellery making and whatnot.
It isn't so strange when you get that the supposed gurus of these activities are all rich white men - jewellers, hairdressers, makeup artists, cosmetics giants....
That leads to a whole other discussion surrounding power and control, natch, but fashion is a man's game.
People do seem to get very polarised on this stuff!! And really, it's only as sinister as you let it become. Sure if you indoctrinate your kid that pamper = girly stuff! and not pamper = people having fun and dressing up! Then it all gets a bit grim.
At 6, I'd be FORCING the boys to wear sparkles 
Joke. I wouldn't even be forcing the girls. At the party dd went to, one of the girls actually had a Jolly Roger drawn onto her face, and black nail polish (with glitter). There was a fair amount of pinkery, but none of it was essential - they were fairly good at not letting turn into indoctrination about what you Should Do.
