I'd post an image of a woman wearing a frilly short skirt that doesn't fully cover her butt but i'd get banned so picrel is next best thing.

That's how i look at this, it's clothing that doesn't match the body, there's no reason a piece of fabric that's big enough to fully cover her jugs couldn't be there and yet it's not. It's sort of erotic in that way, the same way the lower buttocks of a woman wearing a skirt that's not long enough are.
Also she's got that harness going on between her breasts, if you look at her crotch armor, it's shaped like a highleg bikini and it doesn't cover much of her ass either.
tl;dr there's no reason for the bottom of her breasts to hang out and that's erotic
