Actually, just thinking about it, prior to She-Hulk, I don't really think they've gone that route with female superheroes in the MCU much at all. I can't think of many that have been regularly portrayed as sexualized (exception being Black Widow) or having drop-dead gorgeous actresses (exceptions being, again, Black Widow, Pepper [super hero status because she was briefly powered in Iron Man III and, separately, fought in a suit in Endgame], and Monica [in WandaVision]). In contrast, for the male superheroes, it is regularly a thing.
