i totally understand that.  i'm not that into V4 in default or even with the morphs i've purchased at DAZ.  and i really do think that you should do what you want with your artwork, regardless.  but the NGM Petite morphs work with Morphs++ and NGM.   you should probably ask Posermatic how much they actually scale and how much they just provide gravity.  i haven't done more broad testing than trying pretty much all the presets before just using them, but i assumed (though you know what that does) that the reason NGM petite required NGM and Morphs++ was that it was just preset poses for combining the two.  you might see how they work with just the Morphs++ settings and his custom morph settings at 0.  sorry, i'm rendering right now (and V3 at that), or i'd look into it myself.

maybe i'm misunderstanding the outfit, but i think Conniekat8 said it was a skin tight outfit.  yup, on page 1,  "Especially since making a skin tight piece could go fairly quickly." and maybe i'm totally off, but  i doubt Theron agreed to jump around without a bra or internal support.  she might not be the largest chested woman in the world, but that could still hurt.  but even without it, the outfit itself is stitched to have cups and then reinforced on the underside.  so maybe i'm the one that's totally off, but that's my reasoning. 

i'm sorry, i wasn't trying to say they were mostly not appropriate with Poser clothes.  most Poser outfits wouldn't provide support and couldn't hide a bra, even a strapless one.   but this outfit would provide support.
