>>94812683Those are meant to represent an ideal sort of spandex, and are often explicitly made out of fictional materials. They're intentionally designed to be unrealistically form fitting because they're meant to show off the physique of the hero that's wearing them.
Meanwhile, anime has shit like t-shirts and jackets perfectly wrapping around a woman's massive titties, despite supposedly being normal clothing. That sort of design aesthetic has apparently poisoned stupid tumblrite's perception of clothing, and now they don't realize that panties do not, in fact, hug your skin like tights would, and in situations can be loose in some areas. For example, in the picture in question, you can clearly see that the top of the panties are not hugging Harley's butt, leaving a stretched area of cloth that does not conform to her ass. That's why she appears to have "two butt cracks" because our view of her ass crease in interrupted by loose cloth. Ironically, this is akin to a certain test that they perform on children to test for autism, and these faggots would fail in that regard.
Food for thought, my braindead /co/ poster. This is why nobody respects you guys.
