I'd put as
Glinda, but, really, the hair and outfit she ended up with are more for when she still goes by Galinda.
Anyhoo, here she is, Kristen Chenoweth, straight outta Wicked.. Kind of.
Skin and eyes, as always, are by Enayla
Make-up is Rensims, and I believe the eyelinder is Helaene
Hair and Clothes are Maxis-made.
Nightlife is REQUIRED for the dress, if you don't have Nightlife, use SimsPE to install.
For a more Glinda-looking Sim, I recommend Kavar's wonderful
Vintage hair and the
blue dress from Rose Sims.
Enjoy!
