"Perfect" from Sepia comes in the right color (their "white"

and could be cut and styled appropriately
(you could even twist it before cutting to get the part in the
right place):

(I used one of these for a YnM Muraki wig a couple of years ago;
it came out pretty well.)
As for contacts, I'm trying these guys:
http://www.freakyeyes.com/about.html
EDIT: SCREW THOSE GUYS.
After two emails stating what I was after, with pictures,
the guy gets back to me with
"$900, and you'll want the regular cat-eye pupil
because that's too thin." Which I only stated in both the
emails I sent him. So, as they're unable to cope with, like, reading,
I tried the intimidatingly good
9mmsfx.com.
Who said, in response to
this pic,
"Yeah, $270 for a pair."
They win.
Not cheap, but they look like they're possible to work with...
Hope this info helps...
