I had been hanging on to a bunch of parts wanting to make my Catwoman for some time, and once I started putting it together, other parts suggested themselves by just going with the parts I was using, so it ended up not being according to plan, but building as I go.
DCD Hush Catwoman - chest, head, googles, hands, whip, feet
ML Black Widow - arms
FF movie Invisible Woman - abs, hips
ML15 Psylocke - legs, ankles
Scratch built - belt
various - accessories (Kaiyodo Vash's kitty, AA Dark Angel backpack, McF Domina's bracelets...)
In the last WIP you can see the parts coming together before I worked on things like the feet, whihc is my tried and true method of attaching a foot (inthei case the DCD Hush) top the ankles and joints of a ML foot (Psylocke) and I was fortunate that Psylocke's feet make nice little boots for Catwoman. That little movie Sue's torso worked really well with the Hush torso which has a tiny waist. This was done just before the DCSH Catwoman started hitting the market and since that was SO hard to find I was glad I didn't have to go look for one because I had this. And I ended up liking mine better. It is certainly much more articulated, being able to pose just about any way you please.
At the time this was my best work, and still in my Top 10. Let me know what you think.
