What size does hip wear fit in clothing?

Fleshlight like case for Tomax? I Think ToyDemon should make a case that fits the Venus line-up, they could have accessory's that fit the smaller line ups like the lilith by fitting in plastic piece's

I couldn't find anything, but is there a list of which onaholes work and don't work with the Meiki® Plush Doll (besides tomax, meiki, toysheart)? Would Lolinco Virgo fit or is that pushing the size limits?

For anyone who has the hip plush, is it worth getting? It caught my eye and I was planning to get one and use it with the ZXY if it ever comes back in stock...
