>>2061612it's a 3dcg mod, also known as the "expression body" on the mod catalogue. the body has long legs, big breasts, hips, thighs and ass, and a small waist, giving the body a hourglass shape, which can be exagerated even more with some proportion files on tso2pmx.
there are some models that uses it in the booru; search for HK miku, she has said body with a TDA head.
still, the body has some shortcommings, like the shoulders and arms are weighted differently, so you will have to be more precise on posing it compared to the average 3dcg model
