Emilie de Ravin is a fashion favorite of mine and I love the shoes she wore to the NYC premiere for "Remember Me." She looked angelic in that ensemble (Gianfranco Ferre dress and Burberry shoes). I think I found the closest and affordable matches out there.
'Scarfy' Platform Sandals from Baker's
Two options from H and M:
The one on top comes in cream like Emilie's dress. You can see the cream version here.
Here is another similar dress from Akira, but I prefer the H & M ones.
