The clothes are real. He uses human female models with a Tifa like character head pasted on. Not original but pretty neat if you're into this kind of thing.
@Inversekinematics oh wow! Real human models? I don’t think there’s anyone real with those kind of measurements and curves, lol! I guess there’s a lot of post work and brushing involved! Not surprised though, because borderlines between real and cg but doesn’t quite fit in either camp. All makes sense now!
LOL. I had to edit that bit but I see you caught me napping there. The artist can be found on Kemono party. Not for the faint hearted so be warned.
So, it's clothed (Real human model LOL), Tifa head, and a lot of PS work. He appears to be keeping a lot of Patreons happy, has around 5K following his stuff.
