I have been wondering about this. Especially since NeftOOn Gal's stuff generally doesn't poke through and morphs "itself" if you have the body morph pack which also updates all the clothes to have the same morphs. I am finding the workaround for posing the catsuit still getting pokethru in some of the stock poses. I know you have to turn on the thin knee and ankle morphs, but it just still isn't working anywhere near what I would expect. Not that I'm going to return such a fine product, just seconding the frustration with it.
