Classic femme fatale. Goes back to the time when being modest was a societal norm, so if you wanted to make a woman seem evil you portrayed her as going against said norm - aka make her flaunt her sexuality.
Societal norms have changed, but the idea of the femme fatale stuck around because it's fucking hot.

Sex sorry sex sex SEX sorry SORRY SEX!!

FUCK SEX SORRY

why don't we have sexy heroines then?

Same reason why poisonous creatures are the most eye catching ones in the wild. Their looks convey danger and only those who don't know about it or too stupid to risk their lives are the ones who'd approach them.
And in a story where a heroine exist, it also serve as contrast to those characters.

Atelier is sexy and wholesome as fuck. The one pervert from outside the island even notes how weird it is that they have no body issues.
