Vicky 2 (TWO!), Poser 4 or 5 and lots and lots of magnets.

This was done about 15yrs ago, so no "morph-mirror" scripts. Every magnet was positioned by hand.

Anyway, enjoy:

I gave up because I couldn't find hair that looked even remotely like the original. (The one in that pic is photoshopped) BTW, the .cr2 is long gone, so don't ask for a copy. Wouldn't probably work in "modern" Poser anyway. I guess a few strokes with the Morphbrush and some new shaders really could bring her over "the edge". And a proper set of hair, of course.

But there is a really well done V4 version of 7 of 9 on ShareCG. But as she was done with DAZ Studio "Deformers", you'd have to open the file in Studio and then export the morph as an object or so for use in Poser.
