Continuity mistake: When Elizabeth is writing Sue's name on the 17th square on the calendar, she writes it roughly down the middle. When the shot changes, Sue's name is now on the lower half of the square. (00:45:38)
Continuity mistake: When Sue is leaving the apartment in the Louboutin boots, it shows the red bottoms, but when she is getting in the car, there are no red bottoms on the shoes.
Continuity mistake: When Sue's boyfriend walks to the bathroom door and looks down at the blood on the carpet, he's wearing shorts, but in the next shot, he's suddenly naked.
Answer: The film is depicted in a very fantastical and even "cartoonish" way. It doesn't really take place in "our world" so much as a sort of twisted "fairy-tale" version of it. If you notice, everything is very heightened and extreme. The film explores themes like the impact of aging, beauty standards, and the way women are mistreated and exploited by the industry. So you shouldn't be asking why these things are literally happening, but rather why they're thematically happening. The New Year's Eve special broadcasting nude women builds off the themes; it's more exploitation the film has been analysing. In this "world," it's just accepted. As for the little girl? I took that as a satirical statement on how normalized the mistreatment and exploitation of women in the industry is. It's so normalized that a little girl is idolising it, and her mother is allowing her to see it.
