The only reason I’ve ever heard of her is through comparisons between her and the latest Miss America, measurement-wise, as a statement on how American women’s bodies and body images have changed over the years. This is pretty much what appears in the article Elvis linked. Doesn’t seem like that would be the answer to why we care, though.
Unless I’m missing something or they’re desperate to give away prizes, this looks waaaaaay too easy compared to the last one. I suspect that the tricky part will be the “why would we care?” bit (aside from the fact that it should be “why should we care?”, in my humble opinion).
