Head's looking good, Pimp!
As for clothes, I'd tell you to ask Vivisect, except that no one here has been able to contact him in
months. He was an excellent seamstress... err...
seamstrer? You know what I mean.
I think what you should do is get some fabric from somewhere (i.e. a fabric store, or maybe even an old t-shirt you don't wear anymore, etc.)
Then, if you don't have access to a sewing machine, just get some "liquid-stitch" or similar fabric glue. If you can't find any, hot glue or super glue should work if used properly.
You should be able to cobble something similar to what she's wearing together, although from the pics I can see, I don't have a full idea of what she's wearing.
You could hand-make what she's wearing from the waist up, and if you don't want to make the pants, you could probably modify any old pants, like these on eBay:

(and to think I looked through several pages of Barbie pants for you! THE GIRLINESS! MY EYESSSS!!!
)
*AHEM* Yes, well anyway, those pants do seem to be too skinny, but they're made to order, so you could probably ask that they be made slightly loose. And they also appear to be made of stretchy material. I'm sure there's other pants out there that could work, but that's the best I could find in 5 minutes.
Hope that helps!
P.S.
