The question should have been... Does Barbie need to gain some more realistic measurements? Instead what we have is shock and shame tactics, that use a caricature image to represent a plus size woman that is already marginalised and ridiculed by the media and once again opens the industry up to mockery. Essentially what we're left with is one extreme to another.
Their bodies, of course, have been etiolated, distorted versions of the female form since Barbie was first created by Ruth Handler in 1959, but at least when my own daughters played with them 25-plus years ago, Barbie looked fairly wholesome with her princess outfits, air-hostess uniform, tennis gear, and those impossible-to-put-on trousers and little tops.
