Fair warning: the children shown appear to be dolls, not actual human children, but it is still disturbing:
These seem to be adults dressed as literal demons (one of them has horns on their head) many of whom are carrying (probably fake) children, and all marching through the mud. It’s very unsettling.
This next thing is considerably worse since it appears to involve pictures of actual children (I won’t link it here since it’s NSFL). One of Bakenciagas designers, Lotta Volkova, had what appear to be photos of children in various…bizarre? Situations. If you search her name and instagram, there are websites which have archived her page (which is now private).
Balenciaga is trying to claim they didn’t know anything about this. That seems absurd given the rest of what they are putting out and who is working with them.
