Fan Casting Buxom Beauty Standard in Sort by Tropes

Within various forms of media, there is a prevalent assumption among creators that large breasts automatically make a woman more attractive. This often leads to significant focus on said breasts, or in-universe social norms (or specific Cast Herds) treating larger breasts as absolutely more attractive than smaller ones, sometimes going as far as making it the most important or even sole standard of female beauty — regardless of who the fans think is really the most attractive, or whether there is an in-universe distinction between sexual attractiveness and non-sexual beauty.
