>>2438402depends on the type of loli you want, either a petite girl or a perflat one. and also if you want one for ecchi stuff.
tsumidango's old kancolle models like shimakaze and his old oc are good but they have wide hips, his most "recent" (like 3-4 years ago lol) summer ro 500 has more slim proportions, but only his ocs have full body bits, for the others you need to build them through their underwear mesh or using the parts from his oc characters.
kakomiki has some more like alice from queen's gate, the kodomo no jikan girls, konko (this one being the youngest of the bunch, pretty much toddlercon type), rika from higurashi in a mahou shoujou attire, loli doronjo, setsu and tsukumo-tan, they have lewd bits but only konko and tsukumo can go bare naked, the others have pieces of clothes on like stocking or gloves, like rika and alice.
biggest con for kakomikis's lolis are that some are of his oldest models, so their bone setup can be outdated to the motions shared here, and making them move without seeing chunks of poligons twisting in wrong ways harder.
quappa-el's also has models with full pussy AND ass morphs, and a lot of them young looking...unfortunately they are timed releases, so you have to ask here for his old ones, right now there's one available on his website, a purple witch one. also, he has upped the polygon count on his models with each release, so prepare for some slowdowns in some of them.
another loli model you should search for is pxch's miku, this one was quite sought after half a decade ago, but i feel it should be easy to get now, someone even made an flatchested edit of her. no pussy morphs though, but a pretty puffy one if you're into that.
these two uses have good models too
