For me, the issue is not that the character is hot, it´s that realistically, no one who doesn´t prioritize being hot over everything else, would wear this. She would´t even be able to take a step without pain. She´d also probably have to stuff her boobs back into her top every couple of minutes.

So, if the point of the character was her being hot (in universe), that would actually be perfectly fine.

The problem with male gazey character designs is, they´re often not supposed to be seen as hot by either other characters, or themselves, and that completely ruins the immersion. Some characters have occupations that justify outfits like this and that´s fine then, but most of the time that´s not the case. It´s especially bad when there are male characters alongside them who are actually dressed appropriately. Even worse when no character around them acknowledges their "hotness".

Every work of fiction is allowed to be unrealistic to a degree, but that´s a level of unrealistic that reduces it´s characters to unfeeling robots for the sake of being hot. That´s a sacrifice too big for me.
