Searching For Peter Langner "Melissa&quo

I found a Peter Langner dress that I loved called "Melissa", a mermaid/trumpet shape with a lovely train. It was too expensive where I found it, so I`m searching elsewhere. I`m in San Francisco, but will drive a good long way to pick it up for the right price.

In addition, if someone knows of another beautiful mermaid/trumpet style dress of silk or satin, I would love to know where and when to see it.
