born sexy yesterday 

A movie trope in which a female character has a child-like innocence, naivety, or intelligence while being an attractive, sexualized woman. This allows male characters to teach, dominate, and take care of the woman while being sexually attracted to her. This innocence means the character may make “sexy mistakes” like changing or bathing in front of the male lead while being unaware of her desirability. The best known example of this is Leeloo from The Fifth Element

I wanted to see Poor Things, but apparently Emma Stone is just a born sexy yesterday.
