Emmy Rossum went to an Ecco Domani event in NYC last week -- where she was a good Christian girl.
We're told the shoes the "Phantom of the Opera" star threw on were Christian Louboutin's Fortuna style -- which would set you back $1095.
Rossum's dress -- from "Project Runway" star Christian Siriano's Spring/Summer collection -- goes for $1,000.
Now watch her walk it out.
