Project Runway alum Christian Siriano is once again teaming up with Payless Shoe Source for a shoe collab that will, as usual, barely stay on the shelves. For Fall 2011, Siriano found inspiration in organic matter: plants, animals, and other worldly things. Asking us to pick just one of the platform heels for your fall closet is like asking a model her weight, but if we had to, we’d go with the faux-croc print in emerald green — get it before it’s gone.
