Wow.. Well my answer has surely changed in just over three years. Especially as i've since become a shoe person to the extreme degree.
Updated list-
Christian Louboutin (fairly simple but HOT)
Miu Miu (sparkly, girly, and fun)
Dries Van Noten (sturdy, reliable, with extreme attention to details)
Marni (modern and full of chunk and platform)
Doc Martens (boots- because some days it's nice to be able to be hard on your shoes. on top of it all they manage to be flattering as well!)
