Exactly. My daughter had Barbies and not once did she even consider that the doll was a model for how she should look. She just liked changing the clothes, etc. I’d say the recent push back against the original doll is from the moms (probably SJW types) who are pissed they don’t look like that (as if any woman could).
When Twiggy was all the rage in the 1960s it was impossible for girls with meat on their bones to look good in those cute Carnaby Street fashions. I think all that body conscious stuff came in the 1970s when femnists started jaw jacking about body image.
