I tried for quite a while to make a Hillary Clinton mii, and I just couldn't get it to look right. Sigh. There are some people who, try as I might, I just can't seem to capture within the constraints of the mii options.
Here are some ideas (if you use them, be sure to send 'em over!)
Ben Affleck
Richard Dean Anderson
Crispin Glover
John Cusack
Penelope Cruz
Kristin Kruek
Meg Ryan
Catherine Zeta Jones
